Question

an electric bulb draws a current of 0.2 A when the voltage is 220 v calculate the amount of charge flowing through it ​

Answer 1

Answer:

Potential Difference mentioned here of 220 Volts have no use in taking out amount of charges flowing through the circuit in 1hr.

Since we know that,

I = C/t, where each stands for

I for electric current,

C for charge in electrons,

t refers to time taken.

Coming on to the question

0.2 A = C/1 hr

Where, 1 hr = 60 × 60 s

⇒ 0.2 A × 1 hr = C

⇒ 0.2 × 60 × 60 = C

⇒ 720 C = Charges

Answer : 720 C
