Resistance

Electrical resistance is the measurement of degrees to which an object resists an electric current. The unit of electrical resistance is measured in ohms, symbol Ω. Resistance is in every machine.

Ohms can be measured using the following calculation

R= V/I I=V/R V=RI

Where
R is the resistance of the object, measured in ohms
V is the potential difference across the object, measured in volts
I is the current through the object, measured in amperes
