What are common Current Electricity mistakes in JEE?
Students often confuse similar concepts within Electric current: drift velocity, mobility and their relation with electric current, Ohm's law, electrical resistance, I-V characteristics of Ohmic and non-ohmic conductors, Electrical energy and power, electrical resistivity and conductivity, Series and parallel combinations of resistors, temperature dependence of resistance, and more, rush without diagrams, or apply formulas outside their valid conditions.
