The potential difference applied across a given conductor is doubled. How will this affect (i) the mobility of electrons and (ii) the current density in the conductor? Justify your answers.
(i) Mobility 1 Potential difference
So, if potential difference is doubled, mobility will be halved.
(ii) Current density Potential difference
So, if potential difference is doubled, current density will also be double.
