In a \(\mathrm{p\text{-}n}\) junction diode, the change in temperature due to heating:

1. affects only reverse resistance.
2. affects only forward bias.
3. does not affect the resistance of the \(\mathrm{p\text{-}n}\) junction.
4. affects the overall \(\mathrm{V\text{-}I}\) characteristics of a \(\mathrm{p\text{-}n}\) junction.
