ON19 P12 Q37 Galvanometer with Potential Divider | CAIE A Level 9702 Physics

9702/12/O/N/19: The diagram shows a variable resistor R and two fixed resistors connected in series in a circuit to act as a potential divider. The cell of electromotive force (e.m.f.) 6.0V has negligible internal resistance. A cell of e.m.f. 2.0V and a galvanometer are connected into the potential divider. The resistance of R is varied until the galvanometer reads zero. What is the resistance of resistor R? #9702w19p12 #AScircuitsP1 #ASpotentiometerP1 #ASpotentialDividerP1 #Lv3 AS Ch20 #DCcircuits Playlist    • Ch10 DC Circuits | CAIE 9702 AS Physics   Instagram Pocket Guide (  / etphysics  ) More Resources (https://9702-physics.blogspot.com/) Support us!
