Here is the solution sheet for the optics worksheet I had posted earlier: worksheet – optics – solutions
I will be away from the Internet (again!) for another 10 days. Will be back to school on 15th May.
Read the first chapter of electricity – Electric Current (potential difference, current, resistance, Ohm’s law, series and parallel circuits)– from your textbook during this period.
I will give you a revision worksheet on electric current as soon as I’m back.
