How to check if a DC power supply is a floating source?

A first check would be to check, using a tester, the resistance between each of the AC plug contacts and each of the DC plug contacts. These measurement have to show these as insulated. A second check ...

How can I describe the loading effect of an ohmmeter?

Teaching through humor This is a "trap" set by your eccentric professor. Expect his next question to be, "What are the capabilities of the resistor to power sources?" :-) But I am ...

How can I describe the loading effect of an ohmmeter?

Ohmmeters aren't passive things that "load" a circuit like ammeters or voltmeters. Instead, they have to actively measure the component under test. Ultimately, the equation is simply R = V/...

Tension load cell options

Here is what the inside of a luggage scale looks like: The load cell looks like a cantilever beam load cell. The shear element is an aluminum shape with strain gauges probably bonded to the aluminum ...

Tension load cell options

From a mechanical perspective, as you say, the active element of these devices is almost always a ceramic element that is much stronger in compression than tension, and is therefore designed to ...

RLC equivalent model and Impedance Smith Chart

I keep looking but have not found graphs showing the impedances of circuits at various vales of l&c. If the reactances of the L or C are higher supposedly the impedance seen at resonance will be h

Measuring Vackar Oscillator Output Amplitude and High Frequency Effects

The FET gate is a diode. Normally it is kept reverse biased or at least below the 0.5 - 0.6 volt positive bias with respect to the source where it would start to conduct. Obviously it will start ...
