New cards
2

Resistance

________ is a property of the circuit that resists the current.

New cards
3

Ammeters

________ work by putting them in series with resistors (current is constant for resistors in series)

New cards
4

Ohmic

An ________ circuit part is a circuit part (resistor or capacitor) that maintains the same resistance when the voltage across it or current through it changes- resistance is constant.

New cards
5

volt of potential difference

Capacitance is how much charge a capacitor can hold for each ________.

New cards
6

Internal resistance

________ is measured by hooking a battery up to a resistor and plotting the terminal voltage of the battery as a function of the current through the battery.

New cards
7

Voltmeters

________ work by putting them parallel to parallel resistors.
