Electricity and Circuits

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn. If one component fails, the entire circuit stops working.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which the components are connected across common points or junctions, providing multiple paths for the current. If one component fails, the others can still operate.

What is resistance in a circuit?

Back

Resistance is a measure of the opposition to the flow of electric current in a circuit. It is measured in ohms (Ω) and can slow down the flow of electricity.

Front

What is voltage?

Back

Voltage, also known as electric potential difference, is the measure of the energy per unit charge available to drive the flow of current in a circuit. It is measured in volts (V).

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (A). It represents the amount of charge passing through a point in the circuit per unit time.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, preventing it from passing through. Examples include rubber and glass.

Front

What happens when a circuit is broken?

Back

When a circuit is broken, the flow of electric current stops, and any devices powered by the circuit will not function.

Front

What is a light bulb in a circuit?

Back

A light bulb is a device that converts electrical energy into light energy. In a circuit, it acts as a load that uses the current to produce light.

Front

What is a battery?

Back

A battery is a source of electric current that stores chemical energy and converts it into electrical energy when connected in a circuit.
