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

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)

The formula for     I =

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

 =

 = I

I =

Therefore, the formula for I in terms of P and R is  I =
