Question

9.
of march 2021 if the cost of electrical energy
per kWh.
Calculate the equivalent resistance for the given circuit diagram.

The battery lies in between A and B where A is positively charged and B is negatively
charged​

Answer 1

Answer:

$25 \infty$

Step-by-step explanation:

For V

A

>V

B

Both diodes are forward biased

so equivalent resistance will be the parallel connection of the resistances.

R

eq

=

R

+R

R

R

Substitute the values:

R

1

=

50+50

50×50

=25Ω

If V

A

<V

B

Both of the diodes are reverse biased and they will not let the circuit to be closed.

Therefore, the equivalent resistance of the equivalent circuit will be infinity
