Total rate at which electrical energy is dissipated by the two resistors are V²/R or I²R.
Explanation:
When the two resistors are combined in series then the total resistance gets added.
If [tex]R_{1}[/tex] and [tex]R_{2}[/tex] are in series then total resistance, R =
Total resistance becomes [tex]R_{1}[/tex] + 19 Ω
The total electrical power dissipated is equivalent to the power dissipated.
We know,
Power = V²/R or
Power = I²R
where, V is the potential difference between the ends
I is the current supplied.
Therefore, total speed at which electrical power is consumed by the two resistors are V²/R or I²R.
