Answer:
A) True. Voltmeters measure voltages
C) True. They are placed in parallel
E) True ammeters are used to measure current
Explanation:
The devices for voltage measurement are the voltmeter and ammeter
Voltmeters have very high intense resistance and are placed in parallel
The ammeters have very small resist and are placed in series
Based on this establishment, let's analyze the statements
A) True. Voltmeters measure voltages
B) False has high intense resistance
C) True. They are placed in parallel
D) False ammeters are placed in series
E) True ammeters are used to measure current
F) False ammeters have a low internal resistance
