SUMMARY

The discussion focuses on calculating power dissipation in a circuit involving a current divider with two parallel resistors. The voltage across the parallel resistors was determined to be 26.57V, with a current of 1.171A flowing through the circuit. To find the power dissipated, users are advised to calculate the voltage across the parallel combination and then apply the power formula for each resistor. This method ensures accurate power dissipation calculations in electrical circuits.

i got part (a) by using the equation Vab + E - Ir
Which gives 26.57V (also the current = 1.171A)
Having trouble getting the power dissipated, any ideas?

Welcome to the PF.

You just have a current divider with those two parallel resistors. Find the voltage across the parallel combination of those two resistors, and use that voltage independently to calculate the power dissipated in each resistor.
 
Thanks man, its good be here!
