Question

Calculate the work done in taking a charge of 0.02C from A to B if the potential At A is 20V and that at B is 30V

Answer 1

work done(w)=charge(Q) x potential difference(v)                                                                   Q=0.02C                                                                                                              V,potential between the two points AB,which is 20-30=10                                                   
W=QV   0.02 x 10 = 0.4 juoles
