A voltage source and two resistors are connected in parallel as in the given circuit. Suppose that vs = 150 V, R1 = 50 ohm and R2 = 25ohm .Find the currents i1 and i2 in each resistor.
Right Answer is:
i1 = 3A , i2 = -6A
Given Vs = 150 V, R1 = 50 Ω, R2 = 25 Ω
Since voltage parameter in parallel connected elements is same.
Vs = V1 = V2 = 150 V
∴ i1 = V1 / R1 = 150 / 50 = 3 A
Since the direction of the arrow mentioned is in opposite direction to the actual current flow i2 is considered as negative.
i2 = -V2 / R2 = -150 / 25 = – 6 A
