Question

Find equivalent resistance of the circuit

Answer 1

Answer:

The 12Ω and 6Ω resistors are in parallel, so their equivalent resistance is R

1

=12×6/(12+6)=4Ω.

The 7Ω and 5Ω resistors are in series, so their equivalent resistance is R

2

=7+5=12Ω.

The R

1

=4Ω and R

2

=12Ω are in parallel, so their equivalent resistance is R

3

=12×4/(12+4)=3Ω

Now this R

3

=3Ω and 7Ω are in series, so the equivalent resistance is 7+3=10Ω

So the equivalent resistance of circuit is 10Ω.

Answer 2

Answer:

The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.

Explanation:

The two resistances R1 and R2 of 4 ohms are in series therefore their equivalent resistance,

R' = 4 Ω + 4 Ω = 8 Ω

Now the resistances R', R3 and R4 are in parallel so the equivalent resistance of the circuit would be.

Therefore the equivalent resistance between the two points A and B in the given circuit is 1.85 Ω.
