Ohm's law describes the mathematical relationship between
Resistance, current and power
Power, current and resistance
Current, voltage and power
Resistance, current and voltage
When the length and cross sectional area of the conductor is halved then the resistance..........
will become half
will be doubled
remains the same
will increase by four times
Ohms law states
VI² = R
V/I = R²
R = I/V
V = IR
According to Ohms Law
"I" is directly proportional to "V"
"I" is inversely proportional to "V"
