- P2
- CIRCUITS
- Current= flow of charge around the circuit.
- Unit: Amperes,A
- Potential difference=driving force that pushes current round
- Unit: Volts,V
- Resistance= anything that slows down current.
- Unit: Ohms
- Greater the resistance, the smaller the current.
- Potential difference is V. VOLTAGE
- Resistance increases with temperature
- Currents only flows in one direction through Diode
- Current= flow of charge around the circuit.
- SERIES
- All voltage is shared over circuit
- Current is the same everywhere
- PARALLEL
- Voltage is the same
- Current is shared between branches
- CIRCUITS
- Resistance increases with temperature
