Question

How will you get the equivalent resistence 3 ohm by using three 2 ohm resistors

Answer 1

Answer:

By keeping 2 resistors in parallel & 1 in series with those 2.

Explanation:

Let the 3 resistors be: R1, R2 & R3.

Then, R1 = R2 = R3 = 2 ohm

Put R1 & R2 in parallel position,

1/R4 = 1/R1 + 1/R2

1/R4 = 1/2 + 1/2

Thus, R4 = 1

Now, put R3 in series with the combined resistor R4

We get, R = 1 + 2

Thus, R = 3
