Potential difference and work done

Web12 Sep 2024 · The potential is kept high on the positive terminal and low on the negative terminal to maintain the potential difference between the two terminals. The emf is equal to the work done on the charge per unit charge \(\left(\epsilon = \frac{dW}{dq}\right)\) when there is no current flowing. WebThe potential difference or voltage, is simply an indicator of how much potential energy is gained or lost per coulomb, when it moves from one point to another. It can also be …

Web19 Nov 2024 · The potential difference between two points in an electric field is defined as the work done or the energy that would be required to move one coulomb of charge from one point to another. In symbols: Where, V = potential difference (p.d.) in volt (V) W = work done in driving the charge between the two points in joule (J) WebAs the charge is forced away, work is done to move it, which increases its electric potential energy. More the amount of charge, more will be the work required to force the charge away. Thus, electric potential energy of the charge increases as we go away from the charge center of the field.

WebPotential difference is the work done per unit charge. Worked example. A lamp is connected to a 240 V mains supply and another to a 12 V car battery.Both lamps have the same current, yet 240 V lamp glows more brightly. Explain in terms of energy transfer why the 240 V lamp is brighter than the 12 V lamp. Web16 Apr 2024 · So, potential at a point in an electric field is defined as work done in bringing an unit positive charge from infinite distance to that point. Actually, we are measuring the potential difference between infinity and the required point. But we've named it potential of the point as it is with reference point infinity.
