Parallel Circuits Exit Ticket

Front

What is a parallel circuit?

Back

A circuit that contains more than one path for current flow.

Front

What is the relationship between total current into and out of a junction in a parallel circuit?

Back

The total current into a junction equals the total current out of a junction.

Front

What must always be equal for resistors in a parallel circuit?

Back

Voltage.

Front

What happens to the current in a parallel circuit when more branches are added?

Back

The total current increases as more paths for current flow are created.

Front

How does the voltage across each component in a parallel circuit compare?

Back

The voltage across each component is the same.

Front

If one branch of a parallel circuit is broken, what happens to the other branches?

Back

The other branches continue to operate normally.

Front

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

Back

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

Front

How does adding more resistors in parallel affect the total resistance?

Back

Adding more resistors in parallel decreases the total resistance.

Front

What is the effect of a switch on a parallel circuit?

Back

A switch can open or close one branch without affecting the others.

Front

What is the unit of current?

Back

Ampere (A).
