Answer:
R= 5.4 ohms
Explanation:
Given that
V= 9 V
Power ,P= 15 W
Lets take resistor resistance = R
We know that Power given as
[tex]P=\dfrac{V^2}{R}[/tex]
V=Voltage
P=Power
R=Resistance
[tex]R=\dfrac{V^2}{P}[/tex]
Now by putting the all the values in the above equation
[tex]R=\dfrac{9^2}{15}[/tex]
R= 5.4 ohms
Therefore the resistance of the resister will be 5.4 ohms.
