An ac circuit consist of a pure resistance of 10ohms is connected across an ae supply 230V 50Hz Calculate the:
(i)Current flowing in the circuit.

(ii)Power dissipated

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

True or false graphs must include scales that increase by the same amount

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation
