Solve the formula for the indicated variable. Then use the supplied values to solve the equation.The energy W stored by a capacitor is given by W = 
QV, where V is the voltage across the capacitor's terminals after Q coulombs of electricity have been transferred from one of the capacitor's plates to the other. Solve for Q. How many coulombs have been transferred if W is 0.47 watts and V is 15.8 volts? (All values are approximate.)
A. Q = 
= 3.7 coulombs
B. Q = 
= 0.059 coulombs
C. Q= W2V = 3.5 coulombs
D. Q = 2WV = 15 coulombs
