How do you check OHMS?

A multi meter will allow you to directly measure resistance.

Ohm is the unit of resistance. It is given a capital letter because it was named after a scientist, it is someone's name.

You can measure potential difference and current and then use Ohm's Law:

V = IR

Where

V is potential difference in volts

I is current measured in Amps

R is the resistance measured in Ohms

Example: to test a resistor component, use insulated test probes and crocodile clips to hold the component because you will can get tracking of stray signals across your fingers which would cause errors in the reading..

A digital multi meter is very popular and availabale to accuarately test a resistor. It gives a digital readout eg, 100.00 Ohms, allowing you to read decimal places

where as a moving coil meter will depend on the user's eyesight to read the scale .
