![]() ![]() Investigate the relationship between potential difference, current and resistance for a resistorĪn electric heater used to heat a 1kg mass of Aluminium (SHC 900J/K/kg)Ģ.51 Amps, 8.49 Volts and the temperature was raised through 6 Kelvin in 450 secsĮfficiency = useful energy out / total energy inĪ lamp was used to raise the temperature of 50ml (50ml has a mass of 0.05kg) of water (SHC 4200J/K/kg) by 30 Kelvin. Not really a Core Practical but, again, you are expected to know the shape of the graph and how to obtain it in 10.21 Investigate the relationship between potential difference, current and resistance for a filament lamp The diode is not listed here but you are expected to know the shape of the graph and how to obtain it in 10.21 Simple, clear animation for capacitor discharging through a resistor Simple, clear animation for capacitor charging As you can see in the trace, the battery gets hot!Ī bycycle dynamo creates electricity by spinning a magnet in a coil of wire Measuring the current and voltage whilst an 800mAh rechargeable battery is discharged through a direct short. The current reverses for every half rotation of the coil in the magnetic field. ![]() Displaying results which match all of the below:Ī simple animated gif of an a.c. ![]()
