- AIt has no equivalence to switching circuit.
- BIt is equivalent to series switching circuit.
- CIt is equivalent to parallel switching circuit.
- DIt is a mixture of series and parallel switching circuit.
Explanation:
AND gate is only active when both the inputs are high same as series switching circuit which is active only when both switches are closed.
