Solve the problem using this formula.
-Find $E$, the voltage of a circuit, if $\mathrm { I } = ( 18 + \mathrm { i } )$ amperes and $\mathrm { R } = ( 2 + 3 \mathrm { i } )$ ohms.
A) $( 33 + 56 i )$ volts
B) $( 33 - 56 i )$ volts
C) $( - 18 + 56 \mathrm { i } )$ volts
D) $( - 18 - 56 \mathrm { i } )$ volts

Quizplus · Accepted Answer

To find $E$, use Ohm's Law $E = I \times R$. Multiply $I = (18 + i)$ and $R = (2 + 3i)$ to get $E = (18 + i)(2 + 3i) = 36 + 54i + 2i + 3i^2 = 36 + 56i - 3 = (33 + 56i)$ volts.
