R=P over I squared. Solve for I.

Answer: I=sqrt (P/R)

Step-by-step explanation:

R=p/I^2

Multiple l squared on both sides ...

(I^2) R=p/l^2 (l^2)

R (I^2) = p

Separate I by dividing both sides by R ...

I^2=p/R

Square root both sides ...

I=sqrt (P/R)

R=P/I*2

X (I*2) X (I*2)

R (I*2) = P

/R / R

I*2=P/R

*2 * 2

I=P/R
