Electrical Engineering/Expert Profile

Ask A Question


I have been an electronics engineer for many years. I can answer questions on analog and digital circuits and my specialty is sensors.

Experience in the area

I am the inventor on 27 US patents, and also some foreign ones. Developed sensors for many years. Licensed private pilot (airplane and rotorcraft), have HAM radio license. I'm not an expert in computer networking.

When charging a capacitor from a constant current source, the voltage across the capacitor increases linearly over time.      When charging a capacitor WITH A RESISTOR IN SERIES with a constant voltage

2016-09-14 Difference between rated voltage and nominal voltage under standard from IEC or VDE:

If you are talking about motors, for example, the nominal voltage is the voltage of the system (such as 480 volts).  The rated voltage of the motor is the voltage actually expected at the motor (such as

2016-04-14 tank circuit work:

The LC tank circuit is like an electrical equivalent of a tuning fork: it will continue to oscillate at its resonant frequency.  Here's something I paraphrased from Wikipedia:    A capacitor in a parallel

2016-04-03 npn current:

By convention, current flow is from positive to negative (it is not the direction of movement of electrons)).  So your arrows point the wrong way to indicate current flow.      The emitter current is the
