Electronics 2000

Hi there

Im new to this site and i have noticed that you give advice to electronic questions. Presently im studing electronics and on some of my course work i am having some difficulty in understanding some of the questions. such as,

Q1
A conductor 300mm long moves at a uniform speed of 4m/s at right-angles to a uniform magnetic field of flux density 1.25T. Determine the current flowing in the conductor when:

a) its end are open-circuited

b) its ends are connected to a load of 20 ohm resistance

and,

Q2
Calculate the e.m.f induced in a coil of inductance 12 H by a current changing at the rate of 4 A/s

Any advice or helpfull sites to visit would be much appreciated,

Thanking you in advance

Rich

Please Give more single phase AC circuit Application:

Single-phase power distribution is widely used especially in rural areas, where the cost of a three-phase distribution network is high and motor loads are small and uncommon.
