When a P-type semiconductor is suitably joined to an N-type semiconductor, then resulting arrangement is called P-N junction or P-N junction diode
Depletion region: On account of difference in concentration of charge carrier in the two sections of P-N junction, the electrons from N-region diffuse by the junction into P-region and the hole from P region diffuse into N-region.
Because of diffusion, neutrality of both N and P-type semiconductor is disturbed, a layer of negative charged ions appear near the junction in the P-crystal and a layer of positive ions appears by the junction in N-crystal. This layer is known as depletion layer
Distance of the earth from the moon and the sun is? The distance of the earth from the moon is 2,40,000 miles or24 x 104 miles and that from the sun is 93,000,000 or 93x106 mil
