National 5; Practical electrical and electronic circuits Calculating the value of the series resistor. Measurement and analysis of current and voltage in simple circuits allows us to formulate ...

To understand a series circuit, visualize it. You can do that by making a drawing. Just draw a box, to ... Just as with the power supply, erase a spot but instead of a power supply symbol add a load ...

Show that you know your series circuits from your parallel circuits with BBC Bitesize. BBC Homepage. Skip to content; ... The diagram shows a 6 Ω resistor in series with a 2 Ω resistor.

Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the basics.

An airport runway lighting circuit is another example of a series circuit. Here, the secondary winding of an isolation transformer supplies each bulb. So when a filament burns out, the primary ...

Determining the resistor values and assuring performance of the circuit associated with a photocoupler (also called an optocoupler or optoisolator) is simple in principle, but there are some ...

The resistor’s ability to reduce the current is called resistance and is measured in ohms. One of the main uses of resistors is to regulate the current in circuits containing LEDs and transistors.

Calculating the appropriate resistor values for a photocoupler isn’t complicated, but some basic min/max considerations must be acknowledged in when doing the analysis.
