1 Ampere: 1 ampere current is supposed to be flowing in a conductor if one coulomb of charge flows across section of the wire in one second.
Define drift velocity and derive an expression for it?
When reverse bias is enhanced the electric field at the junction also enhances. At some stage the electric field becomes so high that it breaks the covalent bonds building electron
A step-up transformer works on 220V and gives 2A to an external resistor. The turn ratio between the secondary and primary coils is 2 : 25. Assuming 100% efficiency, Determine the
