ohm`s law
For an electrical conductor, by Ohm`s law:
If V = Voltage across its ends ,
R= resistance offered to current flow
and I = Current flowing through it , then
1. V is directly proportional to I.
2. The ratio V/I is constant and equal to R.
If V = Voltage across its ends ,
R= resistance offered to current flow
and I = Current flowing through it , then
1. V is directly proportional to I.
2. The ratio V/I is constant and equal to R.
If I = 2 Amperes and V = 20 volts then
R = 20/2 = 10 ohms.
R = 20/2 = 10 ohms.
