Revise CIE IGCSE Physics 4.3.2c Current and potential difference in circuits with the question bank and revision guides.
Recall and use in calculations, the fact that: (a) the sum of the currents entering a junction in a parallel circuit is equal to the sum of the currents that leave the junction (b) the total p.d. across the components in a series circuit is equal to the sum of the individual p.d.s across each component (c) the p.d. across an arrangement of parallel resistances is the same as the p.d. across one branch in the arrangement of the parallel resistances • Explain that the sum of the currents into a junction is the same as the sum of the currents out of the junction
