WebA body having specific charge 8 μC/g is resting on a frictionless plane at a distance 10 cm from the wall as shown in the figure. It starts moving towards the wall when a uniform electric field of 100 V/m is applied horizontally towards the wall. If the collision of the body with the wall is perfectly elastic, then the time period of the motion, in second will be . WebThe electric potential difference between points A and B, V B − V A, is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1 V = 1 J/C.

Webunits of electric charge. 1 µC = 10-6 C, 1nC=10-9 nda 1pC = 10-12C Electric charge is additive in nature. The total electric charge of a system is the algebraic sum of all the charges located in the system. For example, let us say that a system has two charges +5C and –2C. Then the total or net charge on the system is, (+5C) + (–2C) = +3C. WebElectric Charge is nothing but the amount of energy or electrons that pass from one body to another by different modes like conduction, induction or other specific methods. This is a basic electric charge definition. There …
WebSep 2, 2024 · Current Density. Current density at any point in a conductor is defined as the amount of charge flowing through per unit cross section of conductor around that point in such a way that area is always tangential to the current. Area is normal to direction of current. J = I / A cos θ. I = J A cos θ. I = J . A. Current density is a vector ... WebAmpere is the SI unit of electric current. The relation between current ( i ), charge ( Q) and time ( t) can be expressed below. i = Q t. Substituting the values of charge, current and time as unity in the above equation, we get the below equation. 1 a m p e r e = 1 c o u l …
