Question:
(a) What is the unknown emfx in a potentiometer that balances when Rx is 10.0Ω, and balances when Rs, is 15.00Ω for a standard 3.000-V emf?
(b) The same emfx is placed in the same potentiometer, which now balances when Rs, is 15.0Ω for a standard emf of 3.100 V. At what resistance Rx will the potentiometer balance?
