What is Ohm's Law
Asked by rudreshshukla672 | 18 Oct, 2020, 10:56: PM
answered-by-expert Expert Answer

Ohm's Law states that the current through two points on a conductor is directly proportional to the potential difference across the two points and inversely proportional to the resistance between them.
 
A device is considered to follow Ohm's Law if the current and the potential difference are directly proportional.
 
Ohm's Law is the basic formula used to calculate the resistance of an element that is connected into a circuit: 

Resistance (measured in ohms) = voltage (measured in volts) divided by current (measured in amps) 

Ohm's Law can also be used to find voltage and current when it is expressed as: 

Volts = amps x resistance 

and 

Amps = volts / resistance.
