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

Learn how to measure current and voltage and the advantages of parallel circuits.

We define the properties of parallel and complex circuits. Unit 5 Segment H: Parallel and Complex Circuits We define the properties of parallel and complex circuits. We examine how to find the ...

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 ...

CMOS current reference circuits play a critical role in modern integrated circuits by providing a stable and reproducible current source that remains unaffected by variations in supply voltage ...

In my previous article on photovoltaic (PV) systems (“ The Highs and Lows of Photovoltaic System Calculations ” in the July 2012 issue), I went through methods to calculate the changes in voltage due ...

When very high currents must be generated, using an array of parallel current-sink circuits eases the power dissipation and I DS requirements for the individual MOSFETs.
