The amount of current flowing through each resistor is directly proportional to its resistance.

• True

• False

Circuits that have more than one path for current flow are?

• Combination Circuits

• Series Circuits

• Parallel Circuits

• I don't know...

In a parallel circuit, the total current flow is equal to the (?) of the currents through all the branches.

• Difference

• Average

• Sum

• Quotient

In a parallel circuit, the total resistance is (?) value resistor.

• Less than the lowest

• Equal to the largest

• Equal to the lowest

• Larger than the lowest

The term “load” refers to the amount of (?) in a circuit branch.

• Voltage

• Current

• Resistance

• Wattage

An increase in (?), not resistance, results in an increase of load.

• Wattage

• Power

• Current

• Voltage
