Description
Physics worksheet containing questions about Circuits, Current & Potential Difference.
Model answers are included
This worksheet covers the following content:
- circuit symbols
- electric current as rate of flow of charge; I = Q / t
- the coulomb as the unit of charge
- the elementary charge e equals 1.6 × 10–19 C
- net charge on a particle or an object is quantised and a multiple of e
- current as the movement of electrons in metals
- conventional current and electron flow
- mean drift velocity of charge carriers
- I = Anev, where n is the number density of charge carriers
- distinction between conductors, semiconductors and insulators in terms of n.
- potential difference (p.d.); the unit volt
- energy transferred: W = VQ
- energy transfer eV = 1/2 mv2 for electrons and other charged particles.
This resource is designed to help students apply their knowledge to questions. This active revision technique ensures that the worksheet will be very useful for students, and will act as a vital revision tool.
