Answer:

R= 5.4 ohms

Step-by-step explanation:

Given that

V= 9 V

Power ,P= 15 W

Lets take resistor resistance = R

We know that Power given as


P=(V^2)/(R)

V=Voltage

P=Power

R=Resistance


R=(V^2)/(P)

Now by putting the all the values in the above equation


R=(9^2)/(15)

R= 5.4 ohms

Therefore the resistance of the resister will be 5.4 ohms.
