Question

use ohms law to find the missing value and the round to the nearest hundreth when necessary if voltage= 36 volts and current 4.8 ampers, find the resistence

Answer 1

Answer:

V =IR

R=V/I

R= 36/4.8=7.5

Hence, R=7.5 ohm

Answer 2

The resistance will be 7.5 ohm.

Explanation:  

According to ohm’s law, current I is directly proportional to the applied voltage. Mathematically,

I ∝ V

I = (1/R) V

As we know that to remove the proportionality sign, we have to put a constant. Here, 1/R is proportionality constant. So,

V = IR  

R = V/I = 36/4.8

R = 7.5 ohm

Which is the required answer.
