Simple circuit controls the rate of voltage change across a capacitor or another load

The circuit in this Design Idealets you set a well-controlledvoltage rate of change, often expressedas the differential dV/dt (instantaneousrate of voltage change over time involts per second). You ...

Lab #3: RL and RC Circuits

OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...

Simple, Low-Cost Capacitor Matcher Replaces Expensive Lab

Matching several capacitors, without needing a really precise value, can be accomplished with a "high-tech" laboratory capacitance meter. But this is cumbersome and overkill, and not everyone has one.

VFC makes simple capacitance meter

When you develop the prototype of a circuit using capacitors or when you replace an old, defective capacitor with a new one, you often need to know the value of the capacitor you use or replace. At ...

Simple Circuit Reduces Relay Coil Power

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...
