The value of the resistance will be 11.1 ohms.
According, to the power formula the power= (current) ^2*Resistance.
Therefore, the resistance= (current) 2 /Power.
The given power is equal to 100 w and the current is 3A.
Therefore, according to the formula resistance is equal to current*2/ Power which is equal to 100/9 (11.1 ohms).
