6. Two copper electrodes placed in copper sulphate solutions of equal concentration are connected to form a concentration cell. (1) What is the cell voltage? (2) If one of the solutions is diluted until the concentration of Cu2+ ions is 1/5th of its original value, what will be the cell voltage after dilution?
how do you define the expertise for this hot line maintenance?
Q . Differentiate between an integrator and differentiator? Integrators 1 Integrators are circuits in which output voltage is proportional to the integral of the input.
Compute the mutual inductance: A long single layer solenoid has an effective diameter of 10 cm and it is wound with 1000 turns/m. There is a small concentrated coil with its p
