Chap 7: Electricity
Just read up what i thought u since i started this chapter esp. difference between series and parallel circuit interms of current,voltage and resistance,dont forget how to test north/south in magnet,the right hand grip rule,drawing the mangnetic field,factors increasing the electromagetic power(Refer to my notes)

Chap 8:Generation of Electricity
Focus on the type of generators i jst thought u,formula for transformers(turn ratios) and finally calculation on electricity bill and these formulaes:
i)Power = energy/times
ii)Current= Power/voltage
iii)To calculate price of electric bills: use this formula
First you total up the energy used/given in the question
A. Energy=kWh e.g: 1.2kW x 3 hours x 30 days = 108 kWh
(Refer to my notes esp. the calculation i did with you)
Secondly you multiply what you get in A to the energy cost
B. Cost of energy consumptions= 108kWh x RM 0.20 = RM 21.60
