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. If one component fails, the entire circuit is broken.

Front

What is the direction of current flow in a circuit?

Back

The direction of current flow is from the positive terminal to the negative terminal.

Front

What materials are considered good conductors of electricity?

Back

Metals such as copper and aluminum are good conductors of electricity.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow through it easily. Examples include rubber, glass, and plastic.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow uninterrupted.

Front

What is an open circuit?

Back

An open circuit is a broken circuit where the current cannot flow due to a gap or break in the path.

Front

What happens if a component in a series circuit fails?

Back

If a component in a series circuit fails, the entire circuit is interrupted and current cannot flow.

Front

What is the role of a switch in a circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of current.

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) of the conductor. It is expressed as V = I × R.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points or junctions, allowing multiple paths for current to flow.
