Power gcse physics. The mains voltage in the UK is 230 V. The power of an electrical component or appliance is given by the equation. Power Current and Voltage.
GCSE Physics Online Recommended for Home Learning. To give energy power x time. Of any electrical component using a lamp as our example.
Calculating power Power can be calculated using. In other words it tells us how much energy is transferred per second. Power energy transferred time taken or power work done time taken Power is measured in watts W or joules per second Js.
Some things that are powerful It is said that power corrupts but actually its more true that power attracts the corruptible. 1 watt 1 joule per second. Power P is the rate at which energy is transformed in a device it is measure in watts W.
The power equation shows that the overall power remains the same P V x I Power Voltage x Current. Power tells us how fast work is done. Power current voltage P I V.
This heat is then lost to the environment it is wasted energy. Using the Power Equation. Energy is measured in joules.
