WebTo calculate internal resistance, we use a potentiometer to first calculate the voltage across the battery, with no current through it. Then we attach a resistor in parallel to the battery and recalculate the voltage across it. Since the current flows, this … WebPotentiometer Diagram The diagram to the right shows the role of a potentiometer in a circuit. The potmeter acts as an adjustable voltage divider, varying the wiper's position …

The principle of a potentiometer is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length. The potentiometer is a simple device used to measure the electrical potentials (or compare the e.m.f of a cell). One form of potentiometer is a uniform high-resistance wire attached to an insulating supp… WebA: Given Data: Mass (m) = 225 g = 0.225 kg.Length of the spring (L) = 40 cm = 0.40 m.Stretched length… question_answer Q: wire has a current of 145 A going to the left. WebA potentiometer wire of length 200 cm has a resistance 10 Ω. It is connected in series with an external resistance and a cell of emf 4V and of negligible internal resistance.
