Question

when a conductor is connected to a 12V battery.0.6A of current flows through it what will be the current value if it's connected to 4.5V battery

Answer 1

Explanation:

v=12

I=0.6A

if,v=4.5

then,i=?

w k t , v=ir

r=v/I

compare both resistance,

12/0.6=4.5/?

?=12/(0.6×4.5)

?=12/2.7

?=120/27

?=4.45A
