Ohm's Law Apparatus

Ohm's Law Apparatus Description The Ohm's Law Apparatus is an educational device designed to demonstrate the relationship between voltage, current, and resistance in an electrical circuit, as defined by Ohm's Law ( V = I R ). It typically includes a variable resistor, a power source, an ammeter, and a voltmeter. This apparatus allows students and learners to observe how changing voltage or resistance affects current, helping to understand fundamental electrical principles.
