# Confusion On Opamp watch

1. Potential at point O is 0 ( zero) as shown in circuit.
a) What would be the potential at point A.Is it Zero?
( But how since,current passes through this point.We know where there's current there's some potential.But Y it is said it's zero (i.e. virtual earth))

Solving this question will be reputed.
2. Yes its zero. Current flows down a potential gradient, this doesn't mean it can't flow through a point of zero potential.

U know ohm's law wht it states tht,potential difference is directly proportional to current.Since there's no potential i.e. zero how the current flows.Do Clarify it.
4. OP: Could I suggest that you delete the other two threads that were created?

It's just to keep the forum tidy.

The potential is zero, there is still a potential difference.

Heyy,what is wrong there?
