Q What is photoelectric effect?
Photoelectric release is the phenomena by which a good number of substances chiefly metals emit electrons under the influence of radiation such as X-rays, γ rays, ultraviolet and even visible light.
The primary coil of an ideal step-up transformer has 100 turns and the transformation ratio is also 100. The input voltage the power are 220 V and 1100 W respectively. Calculat
