The formula i=square root w/r gives the electric current i amperes that flows through an appliance, where w is the power in watts and r is the resistance in ohms. which set of numbers best describes the value of i for the given values of w and r? ( 42.) w=100,r=25 ( 43.)w=100,r=50

I believe the correct form of the given equation is:

I = square root (W / R)                   ---> where both W and R is inside the square root symbol

where,

I = the current

W = the electric power

R = resistance in ohms

Now to solve for the value of I for each set, simply substitute the values of W and R into the equation, that is:

when W=100,R=25

I = square root (100 / 25)
I = square root (4)

I = 2

when W=100,R=50

I = square root (100 / 50)
I = square root (2)

I = 1.414
