Question

When a 24 v battery is connected across a 5 ohm resistor the current in it is 0.4 a what is resistance of the resistor what would be the current through it when it is connected to a battery of 6 v

Answer 1

1 case

r=v/i=24/0.4=60 ohm

case 2

I=v/r

I=6/5=1.2 ampere

Answer 2

Answer:

Given,

v=24v

i=0.4a

r=?

i=v/r

0.4=24/r

r=24/0.4

r=60 ohm

v=6v

r=60 ohm

i=?

i=v/r

i=6/60

i=1/10

i=0.1 a
