Electricity

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

6.3. Volts = V

7. Bulb Parts

7.1. Filament ( Made of tungsten)

7.2. Metal Tip

7.3. Metal Casing

7.4. Glass Casing
