I can't understand question:
What effect would halving the battery voltage have on the power transfer in circuit P?
I guess what they want is for me to work out the power before and after with an equation such as.
P = V^2/R ( I know the voltage and the Resistance)
It's the "power transfer" bit that I can't really understand.
