## 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.

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.
