Front

What is the role of a fuse in preventing circuit damage?

Back

It melts to open the circuit.

Front

Which circuit type can have both series and parallel components?

Front

What is a series circuit?

Back

A circuit where components are connected end-to-end, so the current flows through each component.

Front

What is a parallel circuit?

Back

A circuit where components are connected across the same voltage source, allowing multiple paths for current.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance decreases.

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I × R.
