Q

What is a general resistor?

A

In this text/course, a general resistor is defined as a resistor whose terminal current and voltage depend only on the instantaneous values of each other.

Q

What happens to the measure of the voltage of a battery that is attached negative to positive rather than positive to positive?

A

The sign is reversed (2V becomes -2V)

Q

What is an independent voltage source?

A

The voltage is independent of the rest of the circuit and remains constant regardless of the rest of the circuit.
