Measurement of Resistance



Using multimeter


Digital multimeter 



1. Turn power OFF of the circuit . If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading.

2. Turn dial to Ω , which often shares a spot on the dial with one or more other test/measurement modes .



3. First insert the black test lead into the COM jack.
4. Then insert the red lead into the V Ω jack. When finished, remove the leads in reverse order: red first, then black.
5. Connect test leads across the component being tested. Make sure that contact between the test leads and circuit is good.
6. Read the measurement on the display.
7. When finished, turn the multimeter OFF to prevent battery drain.

  1. If you had financial problems, then it is time for you to smile. You only need to contact Mr. Benjamin  with the amount you wish to borrow at the low rate of 2% ROI and the payment period that suits you and you will have your loan  within three working days. I just benefited for the sixth time a loan of 700 thousand dollars for a period of 180 months with the possibility of paying before the expiration date. Mr Benjamin has been helping me with the loan.Make contact with him and you will see that he is a very honest man with a good heart.His email is  247officedept@gmail.com   and his WhatApp phone number is + 1-989-394-3740 .
