PHYS345 Electricity and Electronics

Hint for P2.4

a. Simple application of Ohm's law.

b. Voltage across the resistor is purportedly unchanged from part a. (Can this really be the case?) What is the new current?

c. Now current is unchanged from part a, but the voltage across the resistor is lower. (Can the specifications of this problem be true either?)
