Question

A circuit has a current of 3.6 A and a resistance of 5.0 Ω.

What is the voltage applied to the circuit?

A. 0.72 V
B. 1.4 V
C. 8.6 V
D. 18 V

Answer 1

Answer:

ohms law says that V=IR

V=3.6*5=18 VOLTS

ANS:D

Explanation:

Answer 2

$\huge\boxed{\fcolorbox{#7fff00}{white}{Hello Dear}}$$\huge\bold\pink{{{{{{Answer}}}}}}$

current l = 3.6 A

Resistance R = 5.0Ω(ohm)

Using ohm's law

The voltage applied to the circuit is the product of the current and resistance.

V = l x R

Here, I = current

V = voltage

R = resistance

V = 3.6 x 5.0

V = 18v

so, option (D) 18V is right answer
