Write the formula of the area of a circle

A = π × r2

Hope this helped!

In an electrical circuit, the current (I) and resistance (R) are directly proportional through the equation, 
                               V = I x R
where V is the potential difference. Having a constant potential difference for the two circuits, 
                           (2 A) x (770 ohms) = (I) x (808 ohms)
Solving for I gives I = 1.906 A.
