simple circuits , series and parallel circuits

Front

What is a parallel circuit?

Back

A circuit that has more than one loop, where if one light goes out, the others stay on.

Front

What is current measured in?

Back

Current is measured in Amps (A).

Front

In a Series Circuit, how is the current distributed?

Back

The current is the same at every point.

Front

What is voltage?

Back

Voltage is the amount of energy gained or lost across two points.

Front

What is the formula to calculate resistance using Ohm's Law?

Back

Resistance (R) = Voltage (V) / Current (I).

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 the unit of voltage?

Back

Voltage is measured in Volts (V).

Front

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of current in a circuit.

Front

What is an open circuit?

Back

A circuit that is not complete, preventing current from flowing.
