Question: Two resistors R1 and R2 are in parallel with each other. Together they carry total current I. (a) Determine the current in each resistor. (b)

Two resistors R1 and R2 are in parallel with each other. Together they carry total current I.
(a) Determine the current in each resistor.
(b) Prove that this division of the total current I between the two resistors results in less power delivered to the combination than any other division. It is a general principle that current in a direct current circuit distributes itself so that the total power delivered to the circuit is a minimum.
