Question

multiple choice 1 point electricity what is the voltage v of an electronic circuit with a current c of 4 - j and an impedance i of 7 + 3j? use the formula v = ci. in mathematics, j = i. 11 + 2j 31 - 5j 28 - 3j 31 + 5j clear my selection

Explanation:

Step1: Recall the formula

The formula is $V = CI$, where $C = 4 - j$ and $I=7 + 3j$.

Step2: Perform multiplication

$$

Since $j^{2}=- 1$, we have:

$$
LATEXBLOCK1
$$

Answer:

$31 + 5j$
