you taught me more in 3 mins than my teacher could in 3 weeks

KEY POINT TO REMEMBER: Useful only has one l and transfer has an s in it. But anyway, GREAT VIDEO!

For those in edexcel, it’s efficiency = Useful energy output over energy output total🤗

Don't you have to times the efficiency by 100 after you divide it?
