What is a measure of the energy transferred per unit time?
That is called power. In SI units, it is measured in Joules / second, which is called Watts.
What is it called when you measure of how much electrical energy carries electrons?
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
How Wm-2 is the unit of energy?
Hello W/m2 is not the unit of energy. Students get confused usually as we use the symbol E for the energy radiated per unit area per second. So it is not only the energy. It is the energy emitted in one second. So J/s which equals to W. Per unit area needs /m2 So W/m2 is not the unit for energy. Only J ie joule is the unit of energy.
Is energy a cycle or flow and why?
Energy does not move around in cycles. The reason is related to the Second Law of Thermodynamics. Here is an example: The energy from the Sun comes to Earth, where it maintains life. From Earth, the energy is radiated out into space, where it gets more and more diffuse. This energy can't be recovered again; it won't get back into the Sun - and most of it will not participate in the creation of new stars, either.
What is power in terms of energy?
Yes, power is the rate of energy production or use. In SI units, power is in Watts. 1 Watt = 1 Joule per second. If you prefer older units, 1 hp (horsepower) = 745.7 watts, and 1 ftlbf(footpoundforce) = 1.356 joule.
What is a measure of the energy transferred per unit time?

What is the measure of energy consumed by a circuit?
voltage- apex :))
What is it called when you measure of how much electrical energy carries electrons?
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
Are joules used to measure frequency?
No, the joule (J) is a unit of energy. Frequency is measured in cycles per second, which is also called hertz(Hz).
A meter used to measure energy consumed is called a?
Won't it be the Wattmeter, for 1W = 1Joule/second? The domestic electricity meter is a kW/hr meter.
How does one measure watts?
heat energy produced in one second.
How many watts is needed to melt one pound of aluminum?
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
How do you convert 1997436.144 Kilojoule to KiloWAtt?
You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.
How fast does the sun's energy travel through space?
Most of the Sun's energy is radiated as light, and other electromagnetic waves. These travel at about 300,000 km/sec.; to be precise, the speed of light is exactly 299,792,458 meters per second.

How do you convert 18 volts of radiant energy to watts?
Volts is not a measure of energy so there is no way to have 18volts of energy. Energy is measured in Joules, or sometimes calories. Watts is a measure of energy transferred per second. In electrical terms, 1 Watt is equal to 1 Volt at a current of 1 Amp. In one second, 1 Watt will transfer 1 Joule of energy.
What does a stars luminosity measure?
Luminosity is the total amount of energy emitted by a star per second.
