- Physics Paper 1
- Falling objects. Energy lost from GPE store= Energy gained in kinetic energy store
- Conduction. Vibrating particles transfer energy to neighbouring particles
- Convection= occurs in liquids and gases. Particles move from hotter to cooler regions
- Current= the flow of electrons. PD= the driving force that pushes the charge around
- Length of wire Increase= resistance increase
- Ohmic Conductors. Resistor at constant temperature. Straight line directly proportional
- Filament Lamp. Current increase, the resistance increases. Less current can flow so the graph is a shallow curve
- Diode. Current in 1 direction
- Light Dependent Resistors. Intensity of light. Bright light the resistance falls
- Thermistor. Hot conditions the resistance drops
- Neutral Wire. Completes the circuit and carries current away. Electricity leaves the neutral wire at 0 volts
- Live Wire. Provides alternating PD at 230 volts. Electricity flows in. Can give you a shock.
