Teaching DSSSB TGT Mock Test 2025 Physics Current, Resistance and Electricity Limitations of Ohm’s Law
The variation of current 'I' with the voltage applied 'V' across the conductor is given by V = k I2, where k is a constant for the conductor. The conductor
1
follow Ohm's law for all values of I
2
follows Ohm's law for negative values of I
3
follows Ohm's law for high values of I
4
does not follow Ohm's law for any values of I
