Question 1

When a jumper is used to short components in a control circuit, a ____ is recommended.&#10;A) low reset&#10;B) toggle switch&#10;C) centrifugal switch&#10;D) fused jumper

Accepted Answer

A fused jumper is recommended because it protects the circuit against excessive current flow in case of a short circuit, preventing damage to the components.

Question 2

The ____ method involves testing the circuit at various locations to determine trouble areas.&#10;A) shotgun&#10;B) fire eye&#10;C) hopscotch&#10;D) jumper

Accepted Answer

The shotgun method involves randomly testing different areas of the circuit to identify where the problem may be occurring. It is a common troubleshooting technique used in electronics repair. The other options (Fire Eye, Hopscotch, Jumper) do not refer to a specific troubleshooting method in electronics.

Question 3

The ohmmeter indicates the amount of potential between two points.

Accepted Answer

The ohmmeter measures an electrical resistance, not the potential between two points. The voltmeter measures the potential.

Question 4

To measure the amount of resistance in a circuit, you use a(n) ____.&#10;A) voltmeter&#10;B) ammeter&#10;C) ohmmeter&#10;D) jumper

Accepted Answer

An ohmmeter is specifically designed to measure resistance in a circuit. A voltmeter measures voltage and an ammeter measures current. A jumper is a type of wire used to make temporary connections in a circuit.

Question 5

In the hopscotch method, you follow a ____ procedure.&#10;A) step-by-step&#10;B) localized&#10;C) multi-location&#10;D) logic

Accepted Answer

The hopscotch method requires the user to follow a designated sequence of steps in order to complete the task at hand. This makes it a step-by-step procedure.

Question 6

Many service technicians use a jumper to short the thermostat contacts.

Accepted Answer

Many service technicians use a jumper to short the thermostat contacts in order to test the system without the need for the thermostat to be operational.

Question 7

The ohmmeter is used to measure the actual amount of electricity flowing in a circuit.

Accepted Answer

The ohmmeter is used to measure the resistance in a circuit, not the actual amount of electricity flowing.

Question 8

The megohmmeter is designed to measure resistance in the range of ____ of ohms.&#10;A) hundreds&#10;B) thousands&#10;C) millions&#10;D) billions

Accepted Answer

A megohmmeter is designed to measure very high resistance values, typically in the range of millions of ohms, which is why it is also known as a megger.

Question 9

Technicians rarely use the hopscotch method of troubleshooting.

Accepted Answer

The hopscotch method of troubleshooting is commonly used by technicians to isolate and identify faults by skipping around non-sequential components or systems to quickly find the problem area.

Question 10

The resistance reading will generally give some indication as to the state of the winding.

Accepted Answer

The resistance reading can indicate if the winding is open, shorted, or has a break. However, it cannot always determine the specific fault, and other tests may be necessary to fully diagnose the issue.
