b) Power = Volts * Current (P=v*i)

c) Power efficiency = useful energy output/energy input * 100

also need to learn that

energy=joules

watt=joules/seconds

megawatt=1 000 000 watts

kilowatt=1000 watt

Answer 1

The way I remember formulas is to write them down.

Every problem that you have to use them in, write them down (every single time!). Saying it as you write helps reinforce the idea.

Mnemonics help too but only if you're the creative type (I can't make up mnemonics to save my life).

Answer 2

make it into a song, that always helps. or use mnemonic devices.
