Answer 1

R1 R2 R3 Given, two wo R = 100 a R 90a R3 = 2000 &=150 {=150 A Equivalent resistance of the eismit Reg = R1 + R2 + R3 - 400+900+200 = 1500R Current in the circuit is I = řez a vo A = 0.01 I = D.O1A i 1 potential at the point a is Electric Va = Va = 15 V 15 V 150 04100 D Electric potential at the location bis b = 15-IRI 15 - 0.01 X 400 = 15 - 4 Il v V = 11 v
