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 loads.

Front

What is the difference between a closed circuit and an open circuit?

Back

A closed circuit allows current to flow, while an open circuit interrupts the flow of current.

Front

What is the unit of electric current?

Back

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

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.

Front

What is a series circuit?

Back

A series circuit is a 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 circuit in which the components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

What is a resistor?

Back

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

Front

What is the function of a battery in a circuit?

Back

A battery provides a source of electric current by converting chemical energy into electrical energy.

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 a load in a circuit?

Back

A load is any component in a circuit that consumes electrical energy, such as a light bulb or motor.
