A star's luminosity is the measure of the total energy radiated by the star in one second.
That is called power. In SI units, it is measured in Joules / second, which is called Watts.
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
The energy transformation that results in increased disorder is called entropy. It is a measure of the randomness or disorder within a system, and it tends to increase over time as energy is converted from one form to another.
To find the number of photons being radiated per second, you need to calculate the energy of each photon first. Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.
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.
The measure of energy output from a star per second is referred to as its luminosity. Luminosity is typically expressed in watts (W) or in terms of the Sun's luminosity, denoted as Lā. This value quantifies the total amount of energy radiated by the star across all wavelengths in a given time period, reflecting its intrinsic brightness.

voltage- apex :))
No, the joule (J) is a unit of energy. Frequency is measured in cycles per second, which is also called hertz(Hz).
Won't it be the Wattmeter, for 1W = 1Joule/second? The domestic electricity meter is a kW/hr meter.
heat energy produced in one second.
The energy transformation that results in increased disorder is called entropy. It is a measure of the randomness or disorder within a system, and it tends to increase over time as energy is converted from one form to another.
You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.
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.

Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.
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.
