When two resistors with the same electrical resistance are connected in series to a 12-volt DC source

When two resistors with the same electrical resistance are connected in series to a 12-volt DC source, 6 watts of electric current is allocated to 2 resistors, which will be equal to the electric current on one of the resistors when these resistors are connected in parallel. To the current source, the voltage at the output of the current source remains unchanged.

Given:
U = 12 B
P = 6W
Decision :
When the resistors are connected in series, the power will be – 2P from this it follows that their total resistance will be U ^ 2 / (2P).
Ppair = U ^ 2 / r = 4P = 24 W.
Answer: 24 W.
