Essential Physics for OCR is a brand new series providing clear progression with challenging material for in-depth learning and understanding. Written by the best-selling author of New Understanding Physics, the texts have been laid out in double page spreads and written in simple, easy-to-understand language. Designed in a contemporary manner, they ensure that students truly understand, engage and reflect upon the topic studied. Fully networkable and editable Teacher Support CD-ROMs will also be available for this series containing worksheets, marking schemes and practical help.... a capacitor. b ( i ) With the aid of a circuit diagram, describe how a capacitor may be charged using a battery and a variable resistor to keep the charging current constant. (ii) The diagram below shows how the p.d. changes with time when a capacitor is charged at a constant current of 16 /iA. ... (iii) Calculate the energy transferred from the capacitor to the resistor when the p.d. decreases from 12V to 3.
