The value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.
<h3>What is a complex number?</h3>
It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have:
The current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms.
As we know,
V = IR
V = (3 + j2)(4 - j3)
j² = -1 (complex part)
After simplification:
V = 18 - j volts
Thus, the value of the voltage is 18 - j volts if the current in a circuit is 3 + j2 amps and the resistance is 4 - j3 ohms option (c) is correct.

Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x =
let
8 = n ⇒ 8 =
, that is
2³ = ( equate exponents )
n = 3
and let
(
) = n ⇒
=
, that is
=
( equate exponents )
n = - 1
then
8 +
(
)
= 3 + (- 1)
= 3 - 1
= 2
