What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow through it, consisting of a power source, conductors, and a load.

Front

What are the two main types of circuits?

Back

The two main types of circuits are series circuits and parallel circuits.

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 is a type of circuit where components are connected across common points or junctions, providing multiple paths for current to flow.

How does current behave in a series circuit?

Back

In a series circuit, the current is the same through all components.

Front

How does current behave in a parallel circuit?

Back

In a parallel circuit, the total current is the sum of the currents through each parallel branch.

Front

What happens to the total resistance in a series circuit?

Back

In a series circuit, the total resistance is the sum of the individual resistances.

Front

What happens to the total resistance in a parallel circuit?

Back

In a parallel circuit, the total resistance is less than the smallest individual resistance.

Front

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit.

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.
