2. Electricity
- VOLTAGE = CURRENT x RESISTANCE
- CHARGE = CURRENT x TIME
- > Series Circuits
- Current is constant
- Voltage varies
- Total resistance should increase
- Current is constant
- > Parallel Circuits
- Voltage is constant
- Current varies
- Total resistance should decrease
- Voltage is constant
- ENERGY = POWER x TIME
- A . C Current
- Live wire
- Fuse
- Switch
- Circuit Breaker
- Resettable unlike a fuse

- Resettable unlike a fuse
- Fuse
- Neutral Wire
- Earth wire
- - Protects the device from excess current
- - Protects the device from excess current
- Live wire
- OHM'S LAW
- If temperature is constant, voltage is directly
proportional to the current in an ohmic conductor
- Length of a wire is directly
proportional to its resistance
- Surface area is inversely proportional
- Surface area is inversely proportional
- If temperature is constant, voltage is directly
proportional to the current in an ohmic conductor
