Answer 1

1)A millimeter, also known as a (amperage), resistance, and other values. Multimeters come in analog and digital versions and are useful for everything from simple tests, like measuring battery voltage, to detecting faults and complex diagnostics. The basic functions and operations of a multimeter are similar for both digital and analogtesters. The tester has two leads-red and black and three ports. The black lead plugs into the "common" port. The red lead plugs into either of the other ports, depending on the desired function volt-ohmmeter, is a handheld tester used to measure electrical voltage, current After plugging in the leads, you turn the knob in the center of the tester to select the function and appropriate range for the specific test. To take a reading, we touch the bare metal pointed end of each lead to one of the terminals or wires to be tested. The voltage (or other value) will read out on the tester 2) Using multimeter by measuring thefield resistance .and also by applying voltage to the field winding and measuring current the field can be tested and checked 3) To take a reading, you touch the bare metal pointed end of each lead to one of the terminals or wires to be tested. The voltage (or other value) will read out on the tester. Electrical grounding can be defined as the process of transferring the immediate discharge of the electrical energy directly to the Earth with the help of the low- resistance wire. Resistance connection between two points in an electric circuit throughwhich the current tends to flow rather tha n along the intended path is called short 4) Current=voltage/resistance
