Meters Flashcards
1
Q
What does a multimeter measure?
A
AC DC current
AC DC voltage
resistance
2
Q
How are voltmeters connected?
A
In parallel
3
Q
Does a voltmeter have high or low resistance and why?
A
It has high resistance and it draws minimal current from the source
4
Q
Does a ammeter have high or low resistance and why?
A
Has low resistance so that they do not add unwanted resistance to the circuit
5
Q
How are ammeters connected?
A
In series
6
Q
Ohmmeters?
A
They have their own power and you can not connect it to a live circuit
7
Q
Wattmeter?
A
- Has 4 test leads , 2 for current and 2 for voltage
- Connect voltage in parallel
- Connect current coil in series
