Question

2. How do you connect three resistors 1 ohm,
4 ohm and 12 ohm to get total 4 ohm
resistance? ​

Answer 1

Answer:

1 ohm is in series with the parallel combination of 4 ohm and 12 ohm

Explanation:

resistance in the parallel combination of 4 ohm and 12 ohm

1/R = 1/4 + 1/12

1/R = 4/12

R = 3

total resistance of the circuit

= 1 ohm +(parallel combination of 4 ohm and 12 ohm)

= 1 + 3= 4 ohm
