D. Short answer questions:

1. Write short notes on the following. 

(a) Screwdriver.

Ans: A screwdriver is the basic tool used in electrical panel installation. It is manual or powered, and is used for inserting and removing screws. A screwdriver has a handle and a shaft. A user puts the end tip of the screwdriver into the screw before turning the handle.The shaft is, usually, made of tough steel. It is used to resist bending or twisting.The tip may be hardened to resist wear. Handles are made of wood, metal or plastic.The handle is, usually, hexagonal, square or oval in cross section to improve the grip.This is helpful when twisting the screwdriver and also helps prevent the tool from rolling on the head of the screw. Some manual screwdrivers have interchangeable tips that fit into a socket at the end of the shaft and are held mechanically or magnetically.These often have a hollow handle that contain different types and sizes of tips.  

(b) Megger meter.

Ans: Insulation resistance (IR) quality of an electrical system degrades with time and environment conditions, i.e., temperature, humidity, moisture and dust particles. It also gets impacted negatively due to the presence of electrical and mechanical stress. So, it becomes necessary to check the IR of the equipment at regular intervals to avoid incidences of electrical shock. A megger meter is used as a measuring equipment for insulation resistance tester.

(c) Multimeter.

Ans: Multimeters are test instruments. By operating a multi-position switch on a multimeter, it can be easily be set to function as a voltmeter, an ammeter or ohmmeter. A multimeter has several settings (called ranges) for each type of meter and the choice of AC or DC. Some multimeters have additional features, such as transistor testing, and ranges for measuring capacitance and frequency. Multimeters are available in digital and analog types. 

(d) Combination plier.

Ans: Combination pliers are a versatile hand tool used for gripping objects, bending and shaping materials, and cutting wires and small objects.They typically feature jaws for gripping, cutting edges for wire cutting, and a pivot point for opening and closing.This ability to do multiple tasks makes them a useful tool for different jobs in fields like electrical work, plumbing, and home projects.

(e) Line tester.

Ans: Phase or line tester is used to identify or test the phase of a socket. Line tester is also called ‘neon screwdrivers’ or ‘ test pin’.
