The top circuit, designed by Andre De-Guerin illustrates using a 100uF capacitor to double the battery voltage to obtain 3 volts for the LED. Two sections of a 74HC04 hex inverter are used as a ...

If the LED’s turn-on voltage is lower than the battery voltage, as would be the case with a 6V sealed-lead-acid battery, then you can use a buck converter. Read the associated Circuit Design Idea – ...

A further spray-coating process led to silver nanowires forming only along these sticky lines, creating an intricate network. Using this technique, the researchers fabricated a series of 25cm-long, ...

As shown on the left-hand side of the figure, PPTC device (eg Tyco’s PolySwitch) can be installed in series with the power input to help to protect against damage resulting from electrical shorts, ...

Adding a fourth LED only makes things worse, so series circuits are clearly not the go for lighting multiple LEDs. Parallel circuits These LEDs are connected in a PARALLEL circuit.

The current flowing in a series circuit is the same everywhere. Figure caption, A series circuit with two bulbs and one cell. The ammeter will read the same at points 1, 2 or 3. In series circuits ...
