1
potential difference
The ________ across the capacitor equals the voltage of the devices parallel to the capacitor.
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.
