Pembahasan Soal:

Diketahui:

R₁ = R

I₁ = I

Q₁ = H

I₂ = 2I

Ditanya :

Q₂ = .... ?

Hubungan antara energi kalor dan energi listrik yaitu, energi kalor dan energi listrik memiliki dimensi yang sama. hanya energi kalor biasa dipakai pada peristiwa perpindahan panas, sedangkan energi listrik biasa digunakan pada rangkaian listrik

persamaan kalor 1

$table attributes columnalign right center left columnspacing 0px end attributes row cell Q subscript 1 space end cell equals cell space W subscript 1 end cell row cell straight H space end cell equals cell space I subscript italic 1 to the power of italic 2 italic times R subscript italic 1 italic times t end cell row blank equals cell italic space I to the power of italic 2 R t end cell end table$
