Complex Numbers Are Used in Electronics to Describe the Current $E$

question 77

Multiple Choice

Complex numbers are used in electronics to describe the current in an electric circuit. Ohm's law relates the current in a circuit, I, in amperes, the voltage of the circuit, E, in volts, and the resistance of the circuit, R, in ohms, by the formula E = IR. Solve the problem using this formula
-Find $E$ , the voltage of a circuit, if $I = ( 18 + i )$ amperes and $R = ( 3 + 2 i )$ ohms.

• A) \(( 52 - 39 i )\) volts
• B) \(( 52 + 39 i )\) volts
• C) \(( 18 + 39 i )\) volts
• D) \(( 18 - 39 i )\) volts
