The potential at point a in the circuit is
Webb23 dec. 2024 · electric potential at a point is defined as a work done by me to carry unit charge from infinity to that point What this actually means is that the potential difference between infinity and some point r is the work done per unit charge to move a charge from infinity to that point. Now suppose we have a battery with a potential V. Webb10 apr. 2024 · Hint: Here we have a circuit with three capacitors having capacitance $1\mu F$ each. The potential at a particular point is given and we have to find the potential at another point. For that, we have to find whether the capacitors are in series or parallel combination and using equivalent circuits we have to find the potential.

Webb8 aug. 2024 · We either define it explicitly by saying α=some value, or implicitly by defining some other point not on the circuit as having a value (usually the point is something ground-like or infinitely distant, and the value 0), and then measuring it. The whole point of a potential is it's measured with respect to a reference.
Webb17 okt. 2024 · I have been told that potential in an electric circuit is defined as the work done in bringing a unit test positive charge to that point inside the circuit. Thus it satisfies the premise that potential at the positive terminal is greater and keeps decreasing as we move away from it.
