A device that is Used to measure A.C current is called ___________.
Explanation
A device that is used to measure AC current is called a clamp meter. A clamp meter is a versatile tool that can measure both AC and DC current by clamping around a conductor without the need to disconnect the circuit. It works based on the principle of magnetic induction, where the magnetic field generated by the current flow is detected and converted into a measurable value. Clamp meters are commonly used by electricians and technicians to troubleshoot electrical systems and ensure proper current measurements.Rate this question:

When cleaning electrical equipment, you should use ___________.
Explanation
When cleaning electrical equipment, it is important to use water and soap. This combination is safe and effective in removing dirt, dust, and grime from the equipment without causing any damage or risk of electrical shock. Water is a non-conductive substance, and when mixed with soap, it helps to break down and remove any contaminants on the surface of the equipment. Using water and soap ensures that the equipment is thoroughly cleaned and ready for use without compromising its functionality or safety.Rate this question:

In climbing using a ladder, you should position the ladder at ___________.
Explanation
When climbing using a ladder, it is important to position the ladder at a 75-degree angle. This angle provides the optimal balance between stability and reach. If the ladder is positioned at a smaller angle, it may be unstable and prone to tipping over. On the other hand, a larger angle may cause the ladder to slide away from the surface it is leaning against. Therefore, a 75-degree angle ensures that the ladder is secure and allows the climber to safely reach their desired height.Rate this question:

The electrolytic capacitor's high capacitance and ability to handle high voltage make it suitable for this purpose.Rate this question:
- 16.
A starting capacitor is disconnected from the line automatically if it reaches 75 % of its __________.
Explanation
A starting capacitor is disconnected from the line automatically if it reaches 75% of its rated speed. This is because the starting capacitor is designed to assist in the initial startup of a motor or equipment. Once the motor or equipment reaches its rated speed, the starting capacitor is no longer needed and can be disconnected to prevent any damage or interference with the normal operation of the motor or equipment.Rate this question:
- 17.
A motor rated with a full load current of 100 meters amperes can be wired with cable rated 250 percent __________.
- 18.
To reverse rotation of a 3-phase electric motor ___________.
- 19.
To reverse the rotation of a single-phase motor is by interchanging the leads of a ___________.
Explanation
To reverse the rotation of a single-phase motor, the leads of the starting winding need to be interchanged. The starting winding is responsible for providing the initial torque to start the motor in the desired direction. By swapping the leads of the starting winding, the magnetic field generated by the winding will change direction, causing the motor to rotate in the opposite direction. This reversal of rotation can be useful in certain applications where the motor needs to operate in different directions based on the desired operation.Rate this question:
- 20.
The maximum spacing for convenience outlet in a continuous wall is __________.
Explanation
The maximum spacing for convenience outlets in a continuous wall is 3.6 meters. This means that there should be an outlet available every 3.6 meters along the wall for convenience and accessibility. This spacing ensures that there are enough outlets for electrical devices and appliances to be plugged in without the need for long extension cords or overcrowding of outlets.Rate this question:
