5, Find the total capacitance if two capacitors of 20 Îźf and 5 uf are connected in seriesand if they are connected in parallel.

Answer»

Given c1 = 20 micro f, c2 = 5 micro f

For capacitors connected in seriesTotal Capacitance= 1/(1/c1 + 1/c2)= 1/(1/20 + 1/5)= 1/(1 + 4)/20= 20/5 = 4 micro f

For capacitors connected in parallelTotal Capacitance= c1 + c2= 20 + 5= 25 micro f
