DC - Parallel

Lights connected in parallel have the same voltage across each light

• True

• False

The more resistors connected in parallel the greater the total resistance

• True

• False

Resistors in a parallel circuit can simply be added together.

• True

• False

The total resistance in a parallel circuit is always less than the lowest individual resistance.

• True

• False

Current from the supply in a parallel circuit is equal to the sum of the branch currents.

• True

• False

When there is an open-circuit in a branch of a parallel circuit, the total power will

• remain the same

• stop flowing

• increase

• decrease

The total power consumed in a parallel circuit is:

• equal to one branch of the circuit

• the sum of the power consumed by all branches of the circuit

• the voltage divided by the total resistance

• the current multiplied by the total resistance

Voltage across all components in a parallel circuit is:

• equal

• twice the applied voltage

• less when a component goes open-circuit

• more when a component goes open-circuit

In a parallel circuit comprising of two resistors of equal value, the total resistance will be _________ in relation to each individual resistor.

• tripled

• doubled

• halved

• quadrupled

A short-circuit across a component in a parallel circuit causes the total current to:

• increase

• decrease

• double

• halve
