Series-parallel circuit. The Figure at right shows three impedances; two are connected in parallel and then connected in series with a third impedance. Each impedance can be a pure resistance, a pure ...

If an LED shorts, the string’s FET absorbs the additional voltage and subsequent power dissipation. This circuit can safely handle two shorted LEDs (for red LEDs with Vf = 2.1V) and still maintain ...

The circuit in Fig. 1 can be used to balance the current in two or more parallel strings of series loads where the individual loads vary in voltage, if one load is open or if one load is shorted.

Circuit topologies for connecting LEDs. Erik Ogren looks at the choice between serial and parallel architectures for connecting LEDs. When designing a handheld device with a colour display using white ...

Figure 3: Series-to-parallel conversion simplifies circuit analysis. (Click on image to enlarge) The output impedance is highest at resonance, so the filter resonance frequency must first be ...

Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, current and resistance in these circuits.

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

Series: this refers to lights that are all connected as part of the same circuit, meaning that if one of them burns out, the rest of the strand is taken down with it. Parallel: this refers to ...

The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs ...

However, this is a great time to look at the difference between series and parallel circuits. A Simple Circuit. Just about the simplest circuit you can create uses just one battery and one light bulb.

Complex circuits may have some resistors connected in series, and some connected in parallel. For example, the following combination of resistors shows two resistors connected in series, and three ...
