- 1Energy
A motor is supplied with 800 J of energy and wastes 240 J as heat. Calculate its efficiency as a percentage.
- 2Energy Stores, Transfers and Calculations
A 3 kg object is raised 2 m. Calculate the gravitational potential energy gained. (g = 9.8 N/kg)
- 3Efficiency, Power and Energy Resources
Give the equation for efficiency in terms of energy.
- 4Electricity
A resistor of resistance 15 ohm is connected to a 6.0 V supply. Calculate the current flowing through it. Use V = I x R.
- 5Circuits, Resistance and Components
Two 4 ohm resistors are connected in series. Calculate the total resistance.
