![]() Yeah sure, here I am sharing the Previous Year Physics Question Paper of Chhattisgarh XII Board Why polarisation is not possible in sound waves ? If at any point, electric field intensity is zero, can we accept electric potential will also the same. If not so why not. Write the difference between electrochemical equivalent and chemical equivalent. The north pole of magnet is made to brought near a metallic ring find the direction of induced current in the ring. Write it’s concerting law. How “NOT” gate is obtained from “NAND” gate. Write it’s truth table. What is amplitude modulation ? State Joule’s law of heat production. Magnetic moment of magnetic wire is M. It is bended from one end at a distance of one third in L shape find revised magnetic moment. ![]() ![]() ![]() ![]() ![]() ![]() Rest of the Questions are attached in below file which is free of cost Last edited by Aakashd; June 25th, 2019 at 03:18 PM. |

You need Chhattisgarh XII Board Physics Exam Previous Years Question Paper, I am giving here: When a candle is kept behind a disc of diameter 10 cm.then the shadow of disc is formed opposite the disc (means light is not reaching)but when a whistle is blown behind disc (but shadow is not found). What’s the reason behind change of this behaviour of light & sound. In a hydrogen atom,the electron and proton are bound at a distance of about 0.534 Å. Estimate the potential energy of the system in eV. In which respects does a nearly discharge lead accumlator cell differ mainly from a freshly charged same cell? In its exf or its resistance? A coil is placed in a uniform magnetic field.How should the coil be moved so that there is no e.m.f. indivced in it? If the forward voltage in a semi conductor diode is changed from 0.5 V to 2 V its forward current increased by 1.5 mA. What is resistance of junction diode?
