In [Dave’s] latest episode of the EEVblog he takes a look at constant current dummy loads. These are used to test power supply designs and instead of just chaining resistive loads together every time ...

While it might seem counterintuitive on the surface, there are a number of cases where dumping a large amount of energy into a resistor simply to turn it into heat is necessary to the operation of a ...

Like most engineers, I have used dummy loads spanning DC through RF, and from a few watts to hundreds of watts. Most of these loads were built up from basic resistors, and in some cases special ...

Figured this was the best place to put it.<BR><BR>I'm making 50 ohm RF dummy load with resistors. So I'm using 0.5W metal film resistors in parallel, a fair few of them.<BR><BR>I have 49.9 ohms ...

Mechanics-of-materials expertise plus the power of software make short work of complex shaft problems. • Calculate the deflections in stepped shafts more quickly and accurately by combining ...
