Question

calculate the equivalent resistance between the two points A and B in the following circuit diagram.​

Answer 1

Answer:

Resistors of 3Ω and 2Ω are also in series.

∴ Their equivalent resistance, R

1

=3Ω+2Ω

Resistors of 6Ω and 4Ω are also in series.

∴ Their equivalent resistance, R

2

=6Ω+4Ω

Now, R

are in parallel.

Let R be the equivalent resistance.

Then =
