16 ohm s law is obeyed by many substance but one can t say that it s a fundamental law of nature It s a basic law regarding flow of the current which defines resistance as constant of proportionality The dependence of R was also discussed by ohm s law The potential applied across a conductor and current through it was also one of the important point discussed in this law i What will be resistance across a slab if area is doubled a Resistance will be double c No change I b Resistance will be halved d Resistance will be zero ii on what factor does the resistance depends on a Material only c Material and dimension both b Dimension of conductor only d None of these iii How does resistivity change with temperature a Increases linearly b Decreases linearly c First increases and then decrease d None of the above iv What can you say about the relation between V and I from ohm s law a V depends on I linearly b V depend on I non linearly
