Standard Resistor Values

Standard Resistor Values Fixed resistors come in a variety of types, sizes and resistance values. But to have a resistor available for every possible resistance value calculated, literally millions of individual resistors would need to exist. Clearly this is not practical but ins...

Crest Factor of a Waveform

Crest Factor, (CF) is another mathematical relationship we can use to analyse different types of periodic waveforms. Crest factor, sometimes known as Peak Factor, or Amplitude Factor, is used to define the quality of a particular periodic waveform, since periodic waveforms can ta...

Form Factor of a Waveform

Form Factor, (FF) is a mathematical relationship we can use to analyise different types of periodic waveforms. Form factor is a way of defining the shape, structure and even the quality of a periodic waveform. In other cases form factor can be used to show the "peakiness" of a si...

Superposition Theorem

Superposition Theorem is another circuit analysis tool we can use to find the voltages and currents around a linear electrical circuit. If a circuit contains one or more independent voltage and/or current sources, we can use superposition theorem to find the voltage and/or curren...

Connecting Batteries Together

Batteries Part 2 - Connecting Batteries Together Batteries are ideal for powering hand-held devices as they are available in many different sizes, types and terminal voltage values. But sometimes a single battery on its own is often incapable of providing a high enough voltage or...
