Problem 65
Q

Two 9.49.4-kΩ\textrm{k}\Omega resistors are placed in series and connected to a battery. A voltmeter of sensitivity 1000  Ω/V1000 \; \Omega \textrm{/V} is on the 3.0-V scale and reads 1.9 V when placed across either resistor. What is the emf of the battery? (Ignore its internal resistance.)

A
9.8 V9.8 \textrm{ V}
