Question

The formula for electrical power is P, is P= I^2 R, where I is current and R is resistance. The formula for I in terms of. P and R is

Answer 1

Ans

I = sqrt(P/R)

Step-by-step explanation:

You divide both sides by R first

P/R = I^2 R/R

So,

I^2 = P/R

take the square root of both sides

I = sqrt(P/R)

Answer 2

Answer:

The formula for     I =$\sqrt{P -R}$

Step-by-step explanation:

The formula for electrical power is P, is P= I^2 R, where I is current and R is resistance. The formula for I in terms of P and R

Finding the formula for I in terms of P and R, simply means to make I subject of the formula;

P = I² R

First, subtract R from both-side of the equation

P-R = I²

The next thing to do is to take the square root of  both-side

$\sqrt{P-R}$  = $\sqrt{I^{2} }$

$\sqrt{P-R}$  = I

I =$\sqrt{P-R}$

Therefore, the formula for I in terms of P and R is  I =$\sqrt{P - R}$
