Potencial diffrenece |
|
Answer» The work done to carry a unit positive charge from one point to another point is known as p.d.V=W/Q Potential Difference = Work Done/Charge that means , V = W/Qnow, starting from W , moves to Q to make VThe amount of work done to move a charge from one point to the other is called potenial difference . The SI unit of Potential Difference is Volt (V).We define the SI unit of Potenial Difference as :- 1Volt = 1Joule/1coulomb Starting from 1Joule to 1coulmob to make 1volt:- When 1joule of work is done to move a charge of 1coulomb from one point to the other then rhe potenial difference is said to be 1Volt.The instrument which is used to measure potenial difference is know as Voltmeter , which is connected always in parallel beacause of its high resistivity. |
