Revision 2 Part B<br />
iv) What assumptions have you now made<br />
Circuit analysis<br />
One <strong>of</strong> the fundamental techniques in electricity is circuit analysis. The<br />
algebra is usually easier if you work either with currents as<br />
unknowns or voltages. These are basically restatements <strong>of</strong> Ohm’s<br />
Law.<br />
5. The idea <strong>of</strong> resistance can be extended to describe several<br />
components together. Find the resistance, R AB , between A and B.<br />
(Hint: re-draw the circuit combining the series and parallel<br />
components. You need not do this in one step)
