You’re going to build two simple transistor circuits, each using a single ... the dimmest? 2. Which methods allowed the most current to pass through them? the least? How do you know?

Controlling LEDs is really quite simple. As you know, they need to be current ... current circuits work? If not, then [Giorgos Lazaridis’] guide on LED driving and controlling methods will ...

While this can be done by direct connection with a multimeter, non-contact methods are available too. A great example is this simple wireless AC current detector from [NEW PEW]. The circuit is a ...

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 ...

There’s only one path for the current to follow. This simple circuit is like a one-bulb version of my fairy lights. The ammeter shows the current to be nought point nought six amps Watch what ...
