In National 4 Physics examine the current and voltage in series and parallel circuits to formulate rules and determine unknown values.

Both voltage and current divide in these circuits Electric circuits often consist of several elements, some combined in series and others in parallel. The methods used to analyze ...

Learn how engineers design electrical circuits by calculating the voltage, current and resistance of electrical components.

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

Fig. 3: Capacitors in series. You can also replace one capacitor by putting two capacitors in parallel as shown in Fig. 4. In this case, a .0015 mfd capacitor can be replaced by a .001 mfd and a .0005 ...

In fact, all that's needed is a single voltage or current source and an equivalent resistor — a simple combination that can represent many complex, multi-source circuits.
