1. Michel Faraday of Faraday

Michel Faraday of Faraday's law decided to generate electric current from water flowing in River Thames. 2 conducting plates of length 'a' and width'b' are placed on opposite sides of the river a distance 'w' apart and the plates are immersed completely. The velocity of flowing water is 'v'. If the vertical component of earth's magnetic field is B Derive an equation for the current flowing through load resistor R assuming r as the resistivity of water. If the resistance R= 0, calculate the current if a=100m, b= 5m, v= 3m/s, w= 1500m, B= 50 ?T and r = 100 W.m

Explanation / Answer

according to ohm's law .....

current i=emf/R...

I=emf/R...

induced emf e=B*W*V=

Resistance R=r*a/(a*b)=r/b=

current i=e/R=B*W*V / (r/b).....

ii) c urrrent is maximum
