Web1. The power will remain the same for a particular load as we are not changing the load. so if we increase the voltage, the current will decrease to make the net power consumed by the load same as before. If we increase the current, the voltage will decrease for making the power same. The power will only change when we changes the load. Web5 Jul 2024 · Knowing the relation between the energy and frequency/wavelength of light is important when it comes to figuring out the spectrum of light and energy emitted by the sun. It is worth noting that the energy of a photon is often measured in electron volts (eV), which is the amount of energy needed to move an electron across 1 Volt.
