True

True or False. In a series circuit the resistor that has the most resistance dominates the circuit.

True

True or False. Maximum Power Transfer means to get the maximum possible amount of power from a source to its load.

True

True or False. Parallel circuits are multiple load circuits that have more than one path for current.

True

True or False. The highest resistance in a series circuit drops the most voltage.

True

True or False. The total resistance in a parallel circuit is always less than the lowest branch resistance.

True

True or False. The voltage across an open series load is usually equal to the source voltage.

True

True

Fill in the Blank. ____________ ________ is the voltage or potential energy difference across the resistors

Voltage Drop

In a parallel circuit, what happens to voltage across the load if the load opens?
