Question

Q1: What charge flows through a metallic wire in 1 hour when a constant current
of 0.2 A is flowing through it? [720 C]​

Answer 1

Answer:

720 COULUMB

Explanation:

FOR A CURRENT CARRYING CONDUCTOR THE CHARGE FLOWN IS EQUAL TO THE PRODUCT OF ELECTRIC CURRENT AND TIME FOR WHICH IT FLOWN.

______________________________________

ELECTRIC CURRENT FLOWN = I = 0.2A

TIME TILL FLOWN = T = 1HR = 60 MIN = 3600 SECONDS.

THE CHARGE FLOWN =Q .

______________________________________

FOR A CURRENT CARRYING CONDUCTOR

Q = I × T

Q = 0.5× 3600

Q = 720

SINCE S. I UNIT OF CHARGE IS COULUMB.

THEREFORE

Q = 720 COLOUMB.
