Electric Circuits Flashcards
Charge(I)= Current(Q) x time (s)
.
Current(Q)= Charge(I) / time(s)
.
Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit
.
Potential difference is measured in volts
.
We use a voltmeter to measure potential difference (voltage)
.
voltage= energy divided by charge
.
I= Potential difference
.
Ammeter measures the flow of a current that passes through it (always connected in series)
.
Voltmeters measure the potential difference between two points in a circuit (always connected in parallel)
.
In a series circuit multiple resistors can be put in series together
.
In a series circuit the current is the same at all points
.
In a series circuit the voltage across each component is different
.
Resistors increase the resistance in a circuit
.
resistors oppose the flow of an electric current
.
Resistance is measures in ohms
