Circuits

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electric current to flow easily (e.g., metals), while an insulator resists the flow of electric current (e.g., rubber, plastic).

Front

What is a series circuit?

Back

A series circuit is a type of circuit where components are connected end-to-end, so there is only one path for current to flow.

Front

What is a parallel circuit?

Back

A parallel circuit has multiple paths for current to flow, allowing components to operate independently.

Front

What happens to the current in a series circuit if one component fails?

Back

If one component fails in a series circuit, the entire circuit is broken and current stops flowing.

Front

What happens to the current in a parallel circuit if one component fails?

Back

If one component fails in a parallel circuit, current can still flow through the other paths, so the remaining components stay lit.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of current in a circuit by opening (breaking the circuit) or closing (completing the circuit) it.

Front

What is the purpose of insulation on electrical wires?

Back

Insulation prevents accidental contact with the conductive wire, reducing the risk of electric shock and short circuits.

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): V = I * R.

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).
