Question

Voltage across a short circuit is:

• A. Zero
• B. Infinite
• C. Changing between zero and infinite
• D. Unity

Hint:

Short circuit → zero resistance → zero voltage drop.

Answer 1

The Correct Option is A

A short circuit has negligible or zero resistance. According to Ohm’s law: \[ V = IR \] For \(R = 0\), \(V = 0\) regardless of the current \(I\).
