D.C Circuits, IGCSE 0625 CLASSIFIED WORKSHEET WITH ANSWERS

worksheet contains 32 Mcq’s on D.C Circuits and 6 theory questions with answers. The questions enables the learners to

1. draw circuit diagrams with power sources (cell, battery or a.c. mains), switches (closed and open),
   resistors (fixed and variable), light-dependent resistors, thermistors, lamps, ammeters, voltmeter and light-emitting diodes.
2. state that the current at every point in a series circuit is the same, and use this in calculations.
3. state that the sum of the potential differences in a series circuit is equal to the potential difference
   across the whole circuit and use this in calculations.
4. state that the current from the source is the sum of the currents in the separate branches of a parallel circuit.
5. do calculations on the whole circuit, recalling and using formulae including R = V/ I and those for
   potential differences in series, resistors in series and resistors in parallel.
