The heat produced per unit time, on passing electric current through a conductor at a given temperature is directly proportional to the .....

Answer»

<P>ELECTRIC current
RECIPROCAL of electric current
Square of electric current
Reciprocal of square of electric current

Solution :square of electric current
W = Vlt
`(W)/(t) `= VI
P = VI
` THEREFORE P = IR xx I = I^(2)` R
`therefore ` PRODUCED heat : P =H = `I^(2) ` R Here R is constant`therefore H prop I^(2)`
