Answer 1

b. mark me as brainlest

Answer 2

The equivalent resistance of a network of three 4 ohm resistors can not be (d) 4 ohm.

It is given that we have three identical resistors with a resistance of 4 ohms. We can obtain different values of equivalent resistance from the network of these three resistors.

When we connect all three resistors in series we will get an equivalent resistance of 12 ohms.

When all three resistors are connected in parallel we will get the equivalent resistance of 1.33 ohms.

When two of them are connected in parallel and the equivalent is connected in series we will get the total equivalent resistance of 6 ohms.

The net equivalent resistance can never be equal to 4 ohms in any combination.
