IB Physics Voltage
/A tutorial sheet on voltage and potential difference is given below.
- Is voltage the same as potential difference?
- Define electric potential.
- Define electric potential difference.
- Point A in an electric field has a potential of +15V. Point B in this field has a potential of -12V. (a) What is the potential difference between A and B? (b) What work is done by an external force in moving a +1C charge at a constant speed from A to B? (c) what work is done by the field when a proton moves from A to B?
- Is voltage the same as energy? Explain.
- Is potential difference the same as energy? Explain.
- Sketch the equipotential lines around the point charges +Q and -Q.
- Sketch the equipotential lines around the point charges +4Q and -Q.
- Can electric field lines ever intersect?
- Can equipotential lines ever intersect?
