Power = potential difference across resistance * current
P= i^2 * R
i = E/ equivalent resistance

Since all resistance are in series

Equivalent resistance = 8+12+28= 48

i = 24/48
i= 0.5

Power in R1= 0.5*0.5*8
= 2 watt

Power in R2= 0.5*0.5*12
= 3 watt

Power in R3= 0.5*0.5*28
= 7 watt

Answer:

Power in R1 = 2 watts

Power in R2 = 3 watts

Power in R3 = 7 watts

Compute the total power delivered to the circuit by the 24-volt battery:  12 watts
