Question

What is the resistance offered by a bulb to a current of 7 A and 27V of voltage across it

Answer 1

Answer:

Explanation:

CURRENT , I = 7 A

VOLTAGE , V = 27 V

RESISTANCE,R = ?

ACCORDING TO OHM'S LAW ,

V = I*R

R = V/I

R = 27/7

R = 3.85 OHMS.

THEREFORE THE RESISTANCE OFFERED BY THE BULB =  3.85 OHMS.

HOPE THIS HELPS.

Answer 2

Answer:

Explanation:

R=V/I

  =27/7

  =3.8 ohm
