Grade 12Electric Current
A resistor has initial resistance 'R0' at 0ºC. Now, it is connected to an ideal battery of constant emf = 'v'. If the temperature co–efficient of resistance is α, then after how much time, will its temperature be 'TºC' (mass of the wire = m, specific heat capacity of the wire = S). Assume the resistance varies linearly with temperature neglect heat loss to the surrounding.
