the E-Meter is simply a device that costs five thousand dollars and only measures the resistance of the human body. It does this by having the subject hold two copper cylinders and a simple ...

You’d turn the dial until a meter read zero and read the resistance value from ... we’d like to point out that real analog computers were not this simple. On the other hand, by definition ...

This Design Idea applies essentially the same principle to analog meters under normal operating conditions. Connecting a meter to a voltage source with low internal resistance applies electromagnetic ...

and wire them into an analog mathematics rig. By twisting the potentiometers’ knobs and measuring the resulting voltage or resistance with a digital multimeter, you can perform simple ...
