Answer 1

$\huge\color{black}{ \colorbox{red}{\colorbox{white} {answer\: \: }}}$

I= kV

4 = 13k

k = 4/13

Equation: 1 = 4/13 V

| = 4/13 V

| = 4/13 (18)

1 = 72/13

ANSWER : 1 = 72/13

Answer 2

Answer:

I=KV

4=13K

K=4/13

EQ 1= 4/13v

I=4/13v

I=4/13(18)

I=72/13

Answer I= 72/13

Hope it's clear to you all
