Question

The heat produced in a wire of resistance 'x' when a current 'y' flows through it in time 'z' is given by
(a) x2 × y × z
(b) x × z × y2
(c) y × z2 × x
(d) y × z × x; The heat produced in a wire of resistance 'x' when a current 'y' flows through it in time 'z' is given by
(a) x2 × y × z
(b) x × z × y2
(c) y × z2 × x
(d) y × z × x

Answer 1

The heat produced in a wire of resistance 'x' when a current 'y' flows through it in time 'z' is given by option (b) ) x × z × y2

Explanation:

By joule's law

$H = I^2 Rt$

Where  

I is current  i.e y

R is resistance  i.e x

T is time  i.e z

As per the joules law, the equation is as follows

$H = I^2 Rt$

i.e $y^2 \times x\times z$

therefore $x\times y^2 \times z$

hence the correct option is (b)
