GCSE; WJEC; Electric circuits – WJEC Resistors in series and parallel. Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits.

We examine how to find the total voltage, current and resistance of parallel and complex circuits. We also use a V.I.R. chart to find these things across individual resistors within a circuit. 08 ...

In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the current to pass through. The two resistors have the same potential difference ...

With k = 1/2, the last two terms disappear in equation (7). With a given Vp and I DSS, equation (11) then shows that the drain to source resistance R ds is only dependent on the control voltage V C ...

Break the circuit down into small pairs of series/parallel resistors to tally up the final equivalent resistance, working with pairs makes the parallel calculation much easier (Figure 2). Three ...
