DC - Ch. 8 - Series Parallel

Resistors can be connected in series and parallel in the same circuit

• True

• False

The total resistance of a series–parallel circuit is equal to the sum of the individual resistances.

• True

• False

The total resistance of a series–parallel circuit is best calculated in a number of steps.

• True

• False

The power consumed by an individual resistance in a series–parallel circuit can be determined using the resistor voltage drop and current.

• True

• False

Ohm’s law may be applied to determine the circuit current in a series–parallel circuit

• True

• False

The current drawn by a series–parallel circuit

• is always the same

• depends on the way the resistors are connected

• can only be calculated if the resistor wattage is known

• is proportional to the circuit resistance

Adding resistors in series to a series–parallel circuit will cause the current to

• slowly rise

• slowly fall

• decrease

• increase

The voltage drops across individual components in a series–parallel circuit

• are equal

• are twice the applied voltage

• vary

• are half the applied voltage

In practical applications, series–parallel circuits:

• are never used in real circuits

• are for demonstration only

• have many uses

• are not used any more

An open circuit in one component in a series–parallel combination will:

• always cause current to stop flowing

• have no effect

• change the circuit properties in a way that depends on which resistor open-circuits

• cause a fire
