Question

Find effective resistance of parallel combination of three resistors of resistance 20 40 and 50

Answer 1

Answer:

200/ 9 ohm is the answer

.......

Answer 2

Answer:

radhe radhe

Explanation:

R¹ = 20, R²= 40, R³=50

1/Rp = 1/R¹ + 1/R² +1/ R³

1/Rp = 1/20 + 1/40 + 1/50

1/Rp = 2+4+5/10

1/Rp = 11/10

1/Rp = 10/11

1/Rp = 1.1

Rp = 1.1

the effective resistance of parallel combination of three resistor is 1.1
