DC Parallel Rules/Theories Practice

Adding parallel loads to a circuit will   ?   total circuit current and   ?   the total circuit resistance.

• increase/decrease

• decrease/increase

• increase/increase

• decrease/decrease

A parallel circuit is created where the   ?   divides and follows different paths.

• current

• voltage

• power

• resistance

Adding additional resistors in parallel with those resistors already existing in a parallel circuit will always   ?   the total resistance.

• decrease

• increase

• balance

• maintain

Select the “Product over Sum” formula for determining total resistance in parallel circuits containing two unequal resistances.

The entire   ?   is dropped across each load in a parallel circuit.

• applied voltage

• circuit current

• circuit power

• circuit resistance

Since the total voltage is dropped across each load in a parallel circuit, if one of the loads opens, the current   ?   through the other loads.

• remains the same

• ceases

• increases

• decreases

What is the formula for finding total current in a parallel circuit when individual component currents are known?

The formula is used to find the total   ?   in a parallel circuit when the total resistance and total voltage are known.

• current

• ohms

• power

• wattage
