# Physics- Electricity

The current in a conductor varies as follows: during the first 8 sec there is a linear change from zero to 4 amp; during the next 15 sec the current is constant at 4 amp; during a third period of 20 sec the current decreases linearly to 3 amp. Determine (a) the total charge transferred in the elapsed time of 43 sec, (b) the average current

Sort by:

try drawing the graph of current v/s time. And use the concept the area enclosed by graph with time axis shall give you total charge flown (i.e Ans Part (a) ). Once you've calculated the total charge flown through the conductor, The avg. current is = Total Charge flown/ Total time taken · 3 years, 9 months ago

oh thankyou so much :) · 3 years, 9 months ago

The answer must be (a)146C (b)3.395A · 3 years, 9 months ago

Can you explain to me, how did you get that answers? Thankyou :) · 3 years, 9 months ago

how ? explain more plss · 3 years, 9 months ago
