Under what condition Doppler effect is called red shift and blue shift? For visible light, the bluer part of the spectrum has shorter wavelengths, and the redder part of the spectrum has longer wavelengths. Thus, the Doppler effect for light is called a ‘blueshift’ if the light source is coming toward an observer, and a […]

How is charge related to power?
How is charge related to power? Electrical Energy: The Watt If voltage, (V) equals Joules per Coulombs (V = J/C) and Amperes (I) equals charge (coulombs) per second (A = Q/t), then we can define electrical power (P) as being the totality of these two quantities. This is because electrical power can also equal voltage […]
