The rms value of current in an ac circuit is 25 A, then peak current is

When a p-n junction is reverse-biased,the current becomes almost constant at 25µA. current of when it is forward biased at 200 mV . a current of 75µA is obtained.Find the magnitude of diffusion current when the diode is (a)unbiased ,(b)reverse-biased at 200 mVand (c )forward-biased at 200mV.

A 35% solution of LiCl was electrolyzed by using a 2.5 A current for 0.8 h. Assuming the current efficiency of 90% , find the mass of LiOH produced at the end of electrolysis. ( Atomic mass of Li=7)

If L = 25 mH, C = 1 mF and R = 10Omega then R.M.S current across source is

Two long parallel transmission lines 40.0 cm apart carry 25.0 A and 75.0 A currents. Find an locations where the net magnetic field of the two wires is zero if these currents are in (a) the same direction (b) the opposite direction
