What is the primary source of IR?
- A.
Sun
- B.
Moon
- C.
Earths Surface
Correct Answer
A. SunExplanation
The primary source of IR (infrared radiation) is the Sun. IR is a form of electromagnetic radiation that is emitted by objects due to their temperature. The Sun emits a significant amount of IR as it is a hot celestial body. This IR radiation is responsible for heating the Earth's surface and atmosphere. Other sources of IR include objects on Earth's surface, such as buildings and bodies of water, which absorb and re-emit the Sun's IR radiation. However, the Sun remains the primary source of IR due to its high temperature and continuous emission of this type of radiation.Rate this question:

Which piece of wire and cable test equipment uses the electromagnetic wave pulses to test cables?
- A.
Time domain reflectometer
- B.
Frequency counter
- C.
Signal Generator
Correct Answer
A. Time domain reflectometerExplanation
A time domain reflectometer (TDR) is a piece of wire and cable test equipment that uses electromagnetic wave pulses to test cables. It sends a pulse down the cable and measures the time it takes for the pulse to reflect back. By analyzing the reflected wave, the TDR can determine the length of the cable, locate any faults or disruptions in the cable, and measure the impedance or characteristic impedance of the cable. This makes it a valuable tool for troubleshooting and maintenance of cables in various industries such as telecommunications, networking, and electrical engineering.Rate this question:

Correct Answer
C. DistanceExplanation
In a time domain reflectometer (TDR), the horizontal deflection on the cathode-ray tube represents distance. This means that as the TDR sends a signal down a cable or transmission line, any impedance changes or faults in the line will cause reflections. These reflections are then displayed on the cathode-ray tube, with the horizontal deflection indicating the distance to the impedance change or fault. Therefore, the correct answer is distance.Rate this question:

36 inch 50 ohm cable
- B.
36 inch 25 ohm cable
- C.
12 inch 50 ohm cable
Correct Answer
A. 36 inch 50 ohm cableExplanation
The correct answer is 36 inch 50 ohm cable. This is because the time domain reflectometer (TDR) is used to measure the impedance and detect faults in a cable by sending a pulse down the cable and measuring the reflections. In order to accurately test the cable, it is important to use a cable with the same characteristics as the one being tested. Therefore, a 36 inch 50 ohm cable would be the appropriate standard to use for this purpose.Rate this question:

A time-domain reflectometer display that starts in the upper lect corner of the screen, drops down at mid-screen, and departs in the lower right indicates a(n)
- A.
Short
- B.
Open
- C.
Frayed cable
Correct Answer
A. ShortExplanation
The given display pattern of the time-domain reflectometer indicates a short in the cable. When the display starts in the upper left corner and drops down at mid-screen, it suggests that the signal is reflecting back from a point close to the beginning of the cable. The departure in the lower right indicates that the reflection is occurring near the end of the cable. This pattern is consistent with a short circuit, where the signal is being reflected back due to a direct connection between the conductors.Rate this question:

This is because modern battery chargers are designed to prevent overcharging by automatically adjusting the charging current or voltage when the battery is fully charged. Therefore, leaving the batteries on charge for an indefinite period of time will not cause them to overcharge.Rate this question:
