Solve the Equation for the Current ( I ) Required

Multiple Choice

Solve the equation for the current ( I ) required by a motor when the horsepower, percent efficiency of the motor, and the voltage are known. $$\begin{aligned}h p = \frac { ( E ) ( I ) ( E f f ) } { 746 } \quad \text { where } & l = \text { current in amperes } \\& E = \text { voltage in volts } \\& E f f = \text { efficiency of motor } \\& h p = \text { horsepower }\end{aligned}$$

A) $I = \frac { 746 } { E \times E f f \times h p }$
B) $I = \frac { 746 ( h p ) } { E \times E f f }$
C) $I = \frac { ( h p ) } { 746 E \times E f f }$
D) $I = \frac { E \times E f f } { 746 ( h p ) }$
