Energy, Waves and Electricity
Energy can be transferred through electrical systems and waves. Waves carry energy, and electrical current can transfer energy to components.
What to remember
- Waves transfer energy.
- Sound requires a medium.
- Electromagnetic waves can travel in vacuum.
- Electric current transfers energy through circuits.
- Energy is conserved overall.
Key words
wave — disturbance transferring energy
frequency — cycles per second
current — rate of charge flow
potential difference — energy transferred per charge
conservation — total energy accounted for
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 25 attempts on the same browser.
