The current flowing in a parallel circuit can be investigated by connecting the circuit below. Once more, put one ammeter in position A 1 and record the reading in a suitable table. The current in ...

Parallel circuits are useful if you want components to continue to work, even if one component has failed. This is why our homes are wired up with parallel circuits.

where V LED = the nominal LED voltage at the desired load. This additional low-cost circuitry keeps the CS-pin voltages near ground, and lets the sense resistor (R 1) be at any voltage up to the ...

For some hands-on PCB books action, check out Sydneysider Dave Jones sharing news of the new reference works on his extremely popular EEVblog YouTube channel, earlier this week. After watching the ...

A power-limit circuit can be added to the circuit in Fig. 1 to limit the overall power when there is a large voltage variation for parallel strings of LEDs, with the result shown in Fig. 2.
