Hi there
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
