shows a plot of current `I` through the cross-section of a wire over a time interval of 10s. Find the amount of charge that flows through the wire during this time period.
Text Solution
Verified by Experts
Amount of Charge that flows in 10 seconds is = area under I - t graph `= 1/2 xx 5 xx 5 +(10-5) xx 5 = 12.5 + 25= 37.5 C`
