Compute the heat generated while transferring 96000 coulomb of charge in one hour through a potential difference of 50 V

Answer»

Solution :According to Joule.s LAW of heating the AMOUNT of heat produced is given by
`H = Vt`
where V = 50 V
I = charge/time = 9600 Coulomb/1hr = `(96000)/(60 xx 60) = 80/30 A`
and t = 1 hr = `60 xx 60 ` sec
So `H = 50 xx 80/30 xx 60 xx 60`
4800000 J
` = 4.8 xx 10^6 J`
