True or False: 1. Resistors connected in series always have equivalent resistance greater than any individual resistor. 2. Resistors connected in parallel have equivalent resistance greater than any individual resistor. 3. Most materials have increased resistance as they heat up. 4. A battery's primary function is to provide charge and power to a circuit. 5. The voltage difference between two points in the same (ideal) wire is ALWAYS 0.
