Unit 10 Series Circuits

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
• false

Series circuits are often used for _________ applications.

• signal
• control
• signal and control
• none of these

The 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.

• true
• false

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
• false

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

• true
• false

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

• true
• false

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
• false

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

• proportional
• distributed
• addictive
• the same

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

• true
• false

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.
