Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
