Is power directly proportional to the resistance?
Resistance
The opposition that a substance provides to the flow of electric current is known as resistance. The letter R is used to signify it.
Know that the formula of power is,
is the power measured in watts.
is the resistance measured in Ohms.
is the electric current in Ohms.
Therefore, if current is constant then
Hence, from the mathematical relationship between power and resistance, the power is directly proportional to the resistance.
