What is a short circuit?

I know it happens when current flows between two terminals which have zero potential difference.

Can you guyz help me understand it in depth!

According to my high school knowledge, short circuit happens when the resistence is nearly zero between two terminals WITH potential difference. A large current resulted may overheat the device. Shepherd Ng · 10 months, 3 weeks ago

@Shepherd Ng but zero resistance itself implies that the potential difference is zero as per the eqn. v=r * i Mayank Holmes · 10 months, 2 weeks ago

@Mayank Holmes Potential difference should depend on the battery/power supply and is normally not zero. By V=I*R, as V>0 and R tends to 0, that makes I=V/R go very large. Shepherd Ng · 10 months, 2 weeks ago

Your phrasing does not make sense. Please try rephrasing the question clearly Agnishom Chattopadhyay · 10 months, 3 weeks ago

Short circuit means reduction in impedance. Current in the circuit flow according to source voltage. शरण सतसंगी · 5 months, 3 weeks ago
