Electricity
by Mark Tan

1. More bulbs added = More energy used but has same brightness of bulbs as before.
2. More bulbs added = Dimmer bulbs but less energy used
3. Ways
3.1. Use energy-efficient house appliances
3.2. Turn off all house appliances when not in use
3.3. Close the door and windows when the air-conditioner is turned on
3.4. Use fans more than the air-conditioner
4. Circuits
4.1. Series
4.1.1. More batteries added = Brighter bulbs but more energy used
4.2. Properties
4.3. Parallel
4.3.1. More batteries added = Same brightness of bulbs and saves more energy
5. Conserving Electricity
6. Ohm's Law
6.1. Current = I
6.2. Resistance = R
6.2.1. V = I x R
