The expression you can use is
=> H=I²Rt, where I = intensity of current and R=Resistance of the resistor and t= time taken
Heat,H=square of current x resistance of the resistor x time taken.
H,Heat is a form of energy and energy,e=Pt where P is the power and t is the time taken.
Therefore H=Pt
Since P=I²Rt
we get, H=I²Rt(P =I²Ris substituted)

Heat Produced = I² RT
where i - current, R- resistance, T- Time.

Actually, H = Power * Time

Power = i²R
