Heat produced in a resistance wire of resistance R on passing current is H cal/sec.Then current through resistor = ...... A.

Answer»

`SQRT((H)/(R)) `
`sqrt((H)/(Rt))`
`sqrt((Ht)/(R))`
`(HJ)/(R)`

SOLUTION :`sqrt((HJ)/(R))`
H = `(I^(2)R)/(J)therefore I^(2) = (11J)/(R) "" therefore I = sqrt((HJ)/(R))`
