Question

determine the following quantities for circuits​

Answer 1

Answer:

(a) The equivalent resistance of circuit = 20 + 30 + 50

ohm= 100

(b) The total current from the power supply = 125 / 100=1.25 A

(c) The current through each resistor = 1.25 A

(d) The voltage drop across 20 ohm, 30 ohm and 50 ohm are 25 V, 37.5 V and 62.5 V respectively.

(e) The power dissipated in 20 ohm, 30 ohm and 50 ohm are 31.25 W, 46.875 W and 78.125 W
