| 2 | If 2 joules of energy is required to transfer one coulomb of
charge from one point to another, the potential difference between these points
will be: |
<p class="MsoNormal">1V<o:p></o:p></p> <p class="MsoNormal">2V<o:p></o:p></p> <p class="MsoNormal">4V<o:p></o:p></p> <p class="MsoNormal"><o:p></o:p>6V</p><p class="MsoNormal"><o:p></o:p></p> |
| 3 | What is the amount of current passing through an electric
heater, if it takes 1800C charge pass through it in 3 minute: |
