The electric current existing in a discharge tube is `2.0(mu)A.`How much charge is tarnsferred across a cross-section of the tube in 5 minutes ?

Text Solution

Verified by Experts

`i=2 mu A`
` t = 5 min. = 5 xx 60 sec. `
` q = it = 2 xx (10^-6) xx 5 xx 60 `
` = 10 xx 60 xx (10^-6)C `
` = 6 xx (10^-4)C `.
