#4.1.1a
electric current as rate of flow of charge;
\(I = \dfrac{ΔQ}{Δt} \)
#4.1.1b
the coulomb as the unit of charge
#4.1.1c
the elementary charge e equals 1.6 × 10–19 C
Learners will be expected to know that an electron has charge –e and a proton a charge +e.
#4.1.1d
net charge on a particle or an object is quantised and a multiple of e
#4.1.1e
current as the movement of electrons in metals and movement of ions in electrolytes
#4.1.1f
conventional current and electron flow
#4.1.1g
Kirchhoff’s first law; conservation of charge.
