High Resistance Using Substitution Method is an educational physics laboratory experiment designed to determine the value of an unknown high resistance by comparing it with a known resistance. The experiment demonstrates the principles of electrical measurement, Ohm’s law, and resistance determination using the substitution technique. In this method, an unknown resistance is connected in an electrical circuit, and the corresponding electrical response is observed. The unknown resistance is then replaced with a known variable or standard resistance, which is adjusted until the same electrical response is obtained. Under identical circuit conditions, the value of the substituted resistance provides an estimate of the unknown resistance. The experiment helps students understand measurement accuracy, circuit connections, and the importance of maintaining consistent electrical conditions. Depending on the experimental arrangement, suitable instruments such as a galvanometer, voltmeter, power supply, and resistance box may be used.
