ANot connected at all
BIn series with it
CIn parallel with it
DAt a right angle
Answer & Solution
Correct answer: B. In series with it
1. Current has to pass through the meter to be counted.
2. Voltmeters are connected in parallel with the device measured.
3. Ammeters are connected in series with whatever device's current is to be measured.
4. That way the full current flows through the ammeter.
