Front

What is a series circuit?

Back

A circuit that has only one path for current to flow.

Front

What happens to the brightness of bulbs in a series circuit as more bulbs are added?

Back

The brightness of each bulb decreases.

Front

What must be done for a lamp to light up in a circuit?

Back

Add a source of electric current and close the switch.

Front

What is the essential part missing if a circuit won't work?

Back

Front

What is voltage drop?

Back

The reduction in voltage across a component in a circuit.

Front

What is a parallel circuit?

Back

A circuit that has multiple paths for current to flow.

Front

How does adding more components in parallel affect the overall resistance?

Back

The overall resistance decreases.

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) expressed as V = I × R.
