Answer:

The formula for     I =[tex]\sqrt{P -R}[/tex]

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

[tex]\sqrt{P-R}[/tex]  = [tex]\sqrt{I^{2} }[/tex]

[tex]\sqrt{P-R}[/tex]  = I

I =[tex]\sqrt{P-R}[/tex]

Therefore, the formula for I in terms of P and R is  I =[tex]\sqrt{P - R}[/tex]

The formula for I in terms of P and R is [tex]I = \sqrt{\frac PR}[/tex]

How to rewrite the formula for I

The formula is given as:

P = I^2R

To rewrite the formula for I in terms of P and R, we start by dividing both sides by R.

So, we have:

I^2 = P/R

Take the square root of both sides

[tex]I = \sqrt{\frac PR}[/tex]

Hence, the formula for I in terms of P and R is [tex]I = \sqrt{\frac PR}[/tex]
