PHYS345 Electricity and Electronics

Quiz 2: dc Circuit Analysis

This circuit was suggested as Special Problem 2.2 before our work with mesh and nodal analysis. Please determine the numerical value of the current through the load R by using nodal analysis.

Weird flashlight circuit

The emf of each battery is 1.5 V, the internal resistance r of each battery is 0.2 ohm, and the load resistance R is 7.0 ohm.

Hint: the branch on the right may be simplified to consist of one emf and one resistance.
