Question

tube light draws 0.1 A current from a 220 V supply. What current will this tube light draw

when it is connected to a 110 V supply​

Answer 1

Explanation:

By using the ohm law ,

R= V/I.

Then submit the values in the given formula ,

we get R = 220/0.1= 2200 ohm .

Then V=110 volt and

I = V/R =110/2200

= 0.05 ampere

I hope this helps bro

please mark me as brainliest and thank me

Answer 2

Answer:

It will draw a current of 0.05 A.

Explanation:

Given,

A Tube light draws 0.1 A from a potential difference of 220 V.

Current it will draw from a potential difference of 110 V = R = V/A

= 220/0.1 ohms

= 2200 ohms

= R = V/A

= 2200 = 110/A

= 2200A = 110

= Current = 0.05 A

(Assuming that when the resistance of the connecting wire remains the same.)

Hope this helps.
