A Level Physics worksheet containing questions about the lesson: Circuits, Current & Potential Difference
Model Answers 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.
