1
Q
Charge equation?
A
Charge (C) = current(A) x time (S)
2
Q
Potential difference equation
A
Potential difference (V) = Current (A) x Resistance (Ω)
3
Q
What is an ammeter?
A
Measures current (in amps) ammeter must be placed in series
4
Q
What is a voltmeter?
A
Measures potential difference in a test wire (in volts)
