Question

An electric gadget draws a current 2m from a battery of 12V.Find it's resistance?​

Answer 1

Answer:

R = 6 ohms

Explanation:

I  = 2A

v = 12V

According to ohm's law  :  

V = IR

R = V / I

R = 12 / 2

R = 6 ohms

Answer 2

Answer:

Given: V=12 V

Given: V=12 V I=2.5 mA

Given: V=12 V I=2.5 mALet the resistance be R

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law,

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law, V=IR

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law, V=IR12=2.5×10

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law, V=IR12=2.5×10 −3

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law, V=IR12=2.5×10 −3 R

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law, V=IR12=2.5×10 −3 RR=4.8×10

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law, V=IR12=2.5×10 −3 RR=4.8×10 3

Given: V=12 V I=2.5 mALet the resistance be RBy Ohm's Law, V=IR12=2.5×10 −3 RR=4.8×10 3 Ω
