In the network shown A, B and C are at potentials of 70 V, zero V and 10 V respectively. The false one is 1) Point D is at a potential of 40 V 2) The currents in the sections AD, DB, DC are in the ratio 3:2:1 3) The current in the section AD, DB, DC are in the ratio 1:2:3 4) The network draws a total power of 200 W |
