Question

a 24 volt battery feeds a lamp of 480 ohm. Find current in the lamp neglecting the resistance of connecting wires.

Answer 1

We know,

         V=I ×R
 or,   24= I× 480
 or,      I= 24÷480
 or,      I= 0·05

∴ Current flowing through the wire is 0·05 Ampere.

Answer 2

Answer: 0.05 A

Explanation:

From Ohm's Law

I = 24 V/480 ohm = 1A /20

= 0.05 A

A current of 0.05 A flows through the lamp.
