PHYS345 Electricity and Electronics

Concept: Series and Parallel Combinations

3 resistor circuit

The circuit above has 3 identical resistors and an ideal voltage source.
Before the switch is closed, resistors 1 and 2 have identical currents and voltages.

After the switch is closed, does the current in resistor 1 increase or decrease?
