Voltage is
Also called 'potential difference'
The difference in energy of the electrons leaving and returning a battery
Measured using a voltmeter
All of the above
Resistance is
Measured using an ammeter
Units are 'volts'
How difficult it is for electrons to move through an object
The continuous movement of electrons in a wire
A conductor has _____ resistance. An insulator has ______ resistance.
Low; high.
Negative; positive.
Positive, negative.
High, low.
Series circuits have ________ resistance. Parallel circuits have _______ resistance.
Negative, positive.
High; low.
Low; high.
Positive, negative.
The formula for resistance is:
R = V / I
R = V I
R = V - I
R = I / V
