Chapter 10

When power supplies are connected in series, the circuit voltage remains the same as when only one power supply is connected to it, provided that all the polarities are connected properly.

False

To calculate the total resistance of the circuit: RT = R1 + R2 + R3 + ...

True

To determine the resistance of each resistive element in the circuit, use the formula R = E2/P. E is the rated voltage of the resistor, and P is the rated power of the resistor.

True

Series circuits are often used for _____ applications.

Signal, Control

Kirchoff's Current Law states, "In a series circuit, the current is _____ through the transformer, the conductors, and the appliance."

The same

There can never be variations in the formulas used or the order in which they are used for series circuits.

False

A 115/230V rated motor connected to a 230V circuit must have the windings connected in series so that each winding will receive at least 230V.

False

The power consumed in a series circuit is equal to the power consumed by the largest resistance in the series circuit.

False

A series circuit is a circuit in which a specific amount of current leaves the voltage source and flows through every electrical device in a single path before it returns to the voltage source.

True

If you know the current of the circuit and the resistance of each resistor, the power of each resistor can be determined by the formula P = I2 x R.

True

Kirchoff's Voltage Law states, "In a series circuit, the sum of the voltage drops across all of the resistors equals the applied voltage."

True

No matter how many resistances there are in a series circuit, the sum of the voltages across all of the resistances equals the voltage of the source according to the Law of Proportion.

True

Resistance opposes the flow of electrons. In a series circuit, the total circuit resistance is equal to the sum of all of the resistances in series.

True

The current of the circuit can be determined by the formula I = ES/RT.

True

The opposition to current flow results in a voltage drop of the circuit voltage.
