Series and Parallel Circuits*

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where 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 type of electrical circuit where components are connected across common points or junctions, allowing multiple paths for the current to flow.

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

Back

The total resistance increases when more resistors are added in a series circuit.

Front

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

Back

The total resistance decreases when more resistors are added in a parallel circuit.

Front

What is the formula for calculating voltage in a circuit?

Back

Voltage (V) = Current (I) x Resistance (R) or V = I × R.

Front

What is the SI unit for current?

Back

The SI unit for current is amperes (A).

Front

What is the SI unit for resistance?

Back

The SI unit for resistance is ohms (Ω).

If one light bulb in a series circuit goes out, what happens to the other bulbs?

Back

If one light bulb in a series circuit goes out, all the other bulbs go out as well.

Front

If one light bulb in a parallel circuit goes out, what happens to the other bulbs?

Back

If one light bulb in a parallel circuit goes out, the other bulbs remain lit.

Front

What is potential difference?

Back

Potential difference, also known as voltage, is the difference in electric potential between two points in a circuit.
