Deck 3: Electric Circuits

Question 1

When the path of the current flow is interrupted, the circuit is termed ____________________ or broken.

Answer 1

open

Question 2

A(n) ____________________ circuit is a combination circuit made up of series and parallel circuits and is used only sparingly in the industry.

Answer 2

series-parallel

Question 3

What is the formula for finding the total resistance in a series circuit?

Answer 3

The total resistance Rt in a series circuit is the sum of all the resistances in the circuit: Rt = R1 + R2 + R3 + R4 + .

Question 4

What is the most common source of the electric energy used in the electric circuits of a heating, cooling, or refrigeration system?

Question 5

The total current draw of the entire parallel circuit cannot be determined.

Question 6

The current draw in a parallel circuit is determined for each part of the circuit, depending on the resistance of that portion of the circuit.

Question 7

A series circuit is usually used for devices that are connected in the circuit for safety or control.

Question 8

When an electric circuit is complete so that the current can flow, it is termed ____________________.

Question 9

All electric circuits must have a complete path for electrons to flow through, a source of electrons, and some electric device (load) that requires electric energy for its operation.

Question 10

A(n) ____________________ is an electric circuit that controls some major load in the system.

Question 11

How are the switches in electrical circuits that control parallel loads connected? If the switch opens, what happens to the circuit?

Question 12

A parallel circuit is designed to supply more than one load in the system.

Question 13

The parallel circuit has only one path for the electron flow.

Question 14

The voltage in a series circuit is the same for each device.

Question 15

The ____________________ circuit allows only one path of current flow through the circuit.

Question 16

The most common device supplied with energy is an electric motor.

Question 17

How are the electrical loads that require electrical power for operation usually connected? Why?

Question 18

What is the formula for finding the total resistance of a parallel circuit with two resistances?

Question 19

An electric circuit is the complete path of an electric current, along with any necessary elements, such as a power source and a load.

Question 20

An electric circuit is the complete path of an electric current, along with any necessary elements such as a power source and a load.
