Chapter 4- Eletrical Circuits Flashcards
Charge flow=
Current * time
Potential difference=
Energy / charge
Resistance=
Voltage / current
A charged atom is called an…
…ion
Some ions are…
…charged when they are rubbed as electrons are transferred
Like charges…
…repel
Unlike charges…
… repel
Current is…
…the flow of charge which are electrons
In a series…
… the current is the same on each component
…the voltage of the power supply is the same in each component
… the total resistance in the circuit is equal to the sun of the current
In a parallel circuit…
…the total current is equal to the sum of the current
…. the voltage across each component is the same
Ammeters are connected in a…
Series circuit
Voltmeters are connected through a …
Parallel circuit
As the temperature increases in the lamp…
… the resistance increase
As the temperature increases in the thermistor…
The resistance decreases
Current is…
Directly proportional to the voltage
