QUESTIONS: Electricity Explained

Humans cause electricity to flow by creating an electric circuit. This is basically a path along which electricity can be started and stopped and the direction in which it travels.

Electric Current Worksheet

Conversely, the Law says that a current is inversely proportional to resistance: I = V/R. If you know either of these two variables (I, V, *or R) you can calculate the other using Ohm's Law.

Basic Elements Worksheet

Basic Elements

The function of a resistor is to control the flow of current to other components in the circuit. Resistors are needed because too much electricity can destroy the object it is trying to power.

The function of a capacitor is to store energy in an electric circuit. It blocks direct current (DC) and allows alternating current (AC) to pass.

Resistors Worksheet


Resistors have two ports and are connected to the circuit’s wire in each end so that the current flows through it.

Questions: Resistors

In a series configuration, resisters are connected end-to-end in the circuit. In a parallel configuration, resisters are connected across from each other in an electric circuit.

Conductors and Insulators Worksheet

Conductors and Insulators

Conductors allow a freer flow of electricity because the electrons in the outer shells of the atoms making up that material are loosely bound, so they are freely able to move through the material in the presence of an electric charge.

Types of Electric Circuits

A close (or closed) circuit is when current flows around a complete electrical connection from one end to the other. A circuit is considered open when there is a faulty wire or component in the circuit or if the circuit is switched off.

A short circuit is the opposite of an open circuit. Where an open circuit has unlimited resistance, a short circuit lets a current travel without or with very little resistance, so that excessive current flows through the circuit.

What Are Electric Circuits?

Electric circuits are the heart of numerous electric products, including air-conditioners, refrigerators, and lighting systems. They are the easiest way to transport electric energy from the energy source to the load. But what exactly are they and how do they work?

Electric circuits are closed loops through which electric energy can flow. Energy is transported from the electrical source (usually a battery or electric generator) to the load (which receives the power). The source and load are connected with wires made of a conductive material. 

The rest of this article will look at electric circuits in detail. We’ll look at all the elements that make it up and the different types of them out there so you can better understand this essential element of electricity that powers so much of our modern lives.

The path that electricity travels in a never-ending loop is called an electric circuit. They are very similar to the circulatory system of the human body. Just how blood continually flows around the body and coming back to where it originated, the electrons do the same thing in a circuit. Any circuit has four common components that make this possible. Conductors are the wire or metallic based substances that the electricity flows through. There is a small gap embedded in the conductor where you can close or open (turn on/off) the flow of electricity. The load is the object in the circuit that consumes the electric power, in most cases a light or electronic component. The power source that is making the follow of these electrons possible is called the cell which is often a battery.

Elements of an Electric Circuit

Here are the main elements you will find in most applications:

  • The electric source or battery. This is where the electric energy delivered to the circuit comes from.
  • Controlling devices. These give you control over the flow of electricity and include structures such as switches and resistors.
  • Protective devices. These allow you to protect the circuit from unexpected conditions, such as an abnormal surge of electric energy that could overload the system. Protective structures in an electric circuit can include electric fuses and switchgear systems.
  • Conductors. For simple circuits like those made in classrooms, this usually takes the form of non-insulated copper wires. These and similar conductors create the path through which the electric current is carried from one end to the other.
  • Load. This is the device the electric energy is intended for – the device that consumes the power for some other end. For example, when a bulb acts as the load in an electric current, it consumes the electric energy provided to create an illumination source.

The two fundamental features of any electric circuit are electric current and voltage.

Electric current refers to the movement of a stream of charged particles through an electric conductor. Voltage is the pressure that forces the movement of the electric current through a circuit. It refers to the potential difference between two points in an electric field. 

In terms of a basic electric circuit, voltage acts through the structure of the battery. The electric current is pushed from an area of high potential (the negative terminal of a battery, with greater positive electrons) to that of negative potential (the positive terminal of a battery, with lesser positive electrons). During this flow, the current also passes through the load – in this case, a lightbulb – causing it to light up.

What Are the Different Types of Circuits?

There are numerous types of electric circuits. Some of the most common types of circuits include:


Open and closed circuits are the basic types of circuits depending on whether there is a flow of current through the circuit.

Open circuits are circuits that are broken, incomplete, or otherwise do not facilitate the flow of electric current from the electric source to the load. There is no current flow in an open circuit, and the switch is turned off.


Closed circuits are complete circuits with no break in the current’s path. There is no break in the conducting wires, no insulator hampering the flow of current from source to load, and the switch is turned on. A closed circuit is a “successful” circuit that achieves the aims it was made to achieve.


There is only one path through which the current can flow in this type of circuit. Devices in the circuit are connected one after the other, end to end. Each device has a different voltage but receives the same amount of current. An example of a series circuit is Christmas lights. 


In parallel circuits, there are several paths through which the current can flow. The voltage drops across each component, and they may receive different amounts of current. Parallel circuits are designed so that if one path stops working, the other remains unaffected.

The wiring in your home is an example of parallel circuits. If one lightbulb or electrical outlet in your house stops working, this does not necessarily affect the rest of the electric devices in your home – because of the way the circuit is wired.

Final Thoughts

Electric circuits form the basis of most electric appliances today. Understanding how they work will give you a better understanding of critical parts of modern life, including how your home is wired.
