Question

A Van de Graffgenerator (see figure) is operating so that the potential difference between the high-potential electrode and the charging needles at is 15.0 kV. Calculate the power required to drive the belt against electrical forces at an instant when the effective current delivered to the high-potential electrode is 460 ??. Metal dome Belt Insulator Ground The charge is deposited on the belt at point and transferred to the hollow conductor at point .

Answer 1

Power is given by:

P = V*i

V = Potential difference

i = current

So,

P = 15.0 kV*460 uA

P = 15*10^3 V*460*10^-6 A

P = 6.9 W
