What is power GCSE science?
When work is done on an object, energy is transferred. The rate at which this energy is transferred is called power .
What is the equation for power GCSE?
Power = energy ÷ time.
What topics are in p2 physics?
Subject content
- Energy.
- Electricity.
- Particle model of matter.
- Atomic structure.
- Forces.
- Waves.
- Magnetism and electromagnetism.
- Space physics (physics only)
What is electrical power GCSE?
The power of any device, electrical or mechanical, is a measure of the energy transferred by the device per second. The more ‘powerful’ a device is the more energy it transfers in a given amount of time. All electrical devices have a power rating on them by law.
How is power rating calculated?
Calculate power rating in KVA when you know voltage and output resistance. Use the formula: P(KVA) = (V^2/R)/1000 where R is resistance in ohms. For example, if V is 120 volts and R is 50 ohms, P(KVA) = V^2/R/1000 = (14400/50)/1000 = 288/1000 = 0.288 KVA.
What is GCSE chemistry paper 2?
The second paper covers topics 6-10: the rate and extent of chemical change; organic chemistry; chemical analysis, chemistry of the atmosphere and using resources. Each exam lasts for one hour and 45 minutes and each counts for 50% of the final GCSE mark.
What is P1 physics?
P1: Matter. P2: Forces. P3: Electricity. P4: Magnetism and magnetic fields. P5: Waves in matter.
What is power P?
Electric power definition The electric power P is equal to the energy consumption E divided by the consumption time t: P is the electric power in watt (W).
What are the 2 equations for power?
What is Power?
- P = E t.
- P = W t.
- P = V 2 R.
