Important questions of current electricity
WitrynaElectricity Class 10 Science 1 Mark Important Questions . Q1. – Define electric potential. Answer – Electric potential at a point in an electric field is defined as the work done in moving a unit positive charge from infinity to that point in the electric field. Q2. – State the relation between work (W), change (q) and electric potential (V). Witryna13 cze 2024 · Q.1. The standard resistance coil are made of manganin. Why? Answer: When current flows through a wire its temperature will increase. For alloys like manganin the. temperature coefficient of resistance is very small. Thus, even if the temperature of the coil increases. its resistance will remain constant. Q.2.
