SOLUTION: the voltage in a circuit is given by the equation V= square root of PR, where P is the power in the watts and R is the resistance in ohms, if the voltage in a circuit is 120 volts

Question 83578: the voltage in a circuit is given by the equation V= square root of PR, where P is the power in the watts and R is the resistance in ohms, if the voltage in a circuit is 120 volts and the circuit produces 1500 watts of power, what is the resistance in the circuit?

Given:
.

.
Also given that the voltage (V) is 120 volts, and the Power (P) is 1500 watts.
.
Substitute these values into the equation to get:
.

.
Square both sides of this equation ...
.

.
Squaring the 120 results in 14400. Substituting this results in:
.

.
To solve for R divide both sides of this equation by the multiplier of R which is 1500:
.

.
The division on the left side results in:
.

.
The answer is that the resistance R is equal to 9.6 ohms.
.
Hope this helps you to understand the math manipulations that can be used to solve this
problem.
