Question

Resistor 0f 20 ohm 40 ohm 50 ohm are connected in parallel across a 50 v power source. Find the equivalent resistance of the set and the current in each resistor

Answer 1

Answer:

10.52 ohm

Explanation:

1/r = 1/20+ 1/40 + 1/50

there LCM will be 200 so,

10/200+ 5/200+ 4/200

1/r = 19/200

r = 200/19

r = 10.52 ohm
