Series and Parallel Circuits Flashcard

Front

What is a benefit of using a parallel circuit?

Back

If one light goes out, it does not affect the others.

Front

Current is measured in...

Back

amperes.

Front

The SI units for potential difference is...

Back

volts.

Front

When more light bulbs are added, they all remain bright. Does this describe a parallel or a series circuit?

Back

Parallel circuit.

Front

This circuit does not work because…

Back

the cells are facing each other.

Front

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

Back

The total resistance decreases.

Front

In a series circuit, how does the current behave?

Back

The current is the same through all components.

Front

What is the formula for calculating total resistance in a series circuit?

Back

R_total = R1 + R2 + R3 + ...

Front

What is the formula for calculating total resistance in a parallel circuit?

Back

1/R_total = 1/R1 + 1/R2 + 1/R3 + ...

Front

What is the role of a battery in a circuit?

Back

It provides the potential difference (voltage) needed to drive the current.
