Question

To neglect a voltage source, the terminal across the source are-

1. Open circuited
2. Short circuited
3. Replace by inductor
4. Replace by some resistance

Answer 1

Correct Answer - Option 2 : Short circuited

To neglect a voltage source, the terminal across the sources are short-circuited. Because ideally, the internal resistance of the voltage source is zero.

To neglect a current source, the terminal across the sources are open-circuited. Because ideally, the internal resistance of the current source is infinite.
