Ohm's Law Apparatus Hobby Educational Science

Ohm's Law ApparatusThis apparatus demonstrates the fundamental Ohm's Law of interdependence of current, voltage & resistance in a very simple subtle way.For demonstration of Ohm's law, according to which V / I = R. When connected to an external battery through a pair of color coded terminals with a suitable resistance connected across another pair of terminals, the voltmeter and milliammeter readings are available at the press of the key. Current flowing through the circuit can be controlled through a rheostat knob. With milliammeter 0500mA DC, voltmeter 0-10V DC, rheostat knob, push key, and 4mm socket terminals mounted on top of sheet metal enclosure having scratch resistant epoxy paint coating. Circuit diagram indicating all components printed on top of the enclosure. External battery and resistances not supplied, available optionally
