KP211 Lecture 6: Macro - Conflict Model (Oct. 3, 2016)

A 3-O and a 1.5-O resistor are wired in parallel and thecombination is wired in series to a 4-O
resistor and a 10-V emf device. The potential difference across the3-O resistor is:
A. 2.0V
B. 6.0V
C. 8.0V
D. 10V
E. 12V

Two identical batteries, each with an emf of 18V and an internalresistance of 1 O, are wired in
parallel by connecting their positive terminals together andconnecting their negative terminals
together. The combination is then wired across a 4-O resistor. Thecurrent in the 4-O resistor
is:

A. 1.0A
B. 2.0A
C. 4.0A
D. 3.6A
E. 7.2A
