Consumers do not normally have 'power meters'; they normally have 'energy meters', which are used measure the amount of energy being purchased from the electricity supply company. 'Power meters' are wattmeters, which measure power -i.e. the rate at which you use energy. Energy meters measure energy in units called kilowatt hours, whereas wattmeters measure power in watts. Your electricity supply company isn't really interested in the power of your residence, only the energy consumed.
Sound intensity is measured in watts per square meters, but our eardrums are only moved by the sound pressure measured in newtons per square meters or pascals.
The work done to move the 10 N book 5 meters is 50 Joules (Work = force x distance). The power used is 25 Watts (Power = Work / time).
Power meters work by measuring the flow of electricity in a system using sensors and circuits. They calculate the amount of power generated or consumed by monitoring the voltage and current passing through the system. This data is then used to determine the power usage or generation in watts.

Watts.
The power used by the heater can be calculated using the formula: Power = Voltage x Current. In this case, the power would be 460 volts x 5 amps = 2300 watts.
Electrical power is also measured in Watts.
Watts are used to measure electrical POWER. You can use the mnemonic CAROPWEV to remember this CA=CURRENT measured in AMPERES RO=RESISTANCE measured in OHMS PW=POWER in WATTS EV=ENERGY in VOLTS you can get power by multiplying the current by the voltage.
You are confusing electrical potential (Volts) and power (Watts). The equation for power (watts) is P = VI where V is volts (a measure of electrical "pressure") and I is current in amperes (the rate of flow of electricity). If the system is 120V and the power used is 600W then the current used is 5A. If the system is 240V and the power used is 600W then the current used is 2.5A.
The power would be 350 watts. Power is the rate at which energy is transferred or converted, so in this case, if 350 joules of energy is used per second, the power output would be 350 watts.
Watts measures power. It is abbreviated simply with a W. It is energy used (or work) over time. Thank you. So what does 1 lb = 4.45 N mean using the label used for power? If Watts measures power and is abbreviated with a W and is the label that is used for power, then what is the label used for Work?
2000 watts RMS is equivalent to 2000 watts. RMS (Root Mean Square) is a method used to measure the power of an electrical signal.
