Electric 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.

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, allowing multiple paths for the current to flow.

What is the symbol for an Ammeter?

Back

The symbol for an Ammeter is a circle with an 'A' inside it.

Front

What is the symbol for a Voltmeter?

Back

The symbol for a Voltmeter is a circle with a 'V' inside it.

Front

What is the function of a Fuse in a circuit?

Back

A Fuse is a safety device that protects an electrical circuit by breaking the circuit if the current exceeds a certain level.

Front

What is a Resistor?

Back

A Resistor is a component that resists the flow of electric current, creating a voltage drop.

Front

What does a Light Emitting Diode (LED) do?

Back

A Light Emitting Diode (LED) emits light when an electric current passes through it.

Front

What happens when a circuit is broken?

Back

When a circuit is broken, the flow of electric current stops, and devices in the circuit, like light bulbs, will not work.

Front

What is the role of a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It is expressed as V = I × R.
