how do we connect voltmeter and ammeter and electric circuit what is likely to happen if the position of the instrument are interchanged??
If u can answer all above or any of them u can ?? Please help

Normally, the ammeter is connected in a series to an electrical circuit, due to its low resistance; while the voltmeter is connected in a parallel position to the circuit, as its resistance is very high.
However, if the positions of these devices are interchanged and the ammeter is placed in parallel position; it is likely to be damaged due to the short circuit when the electric current follows the path of low resistance only.

Answer:
Explanation:1. We know that of charge on an electron. c=1.6x10^-19c.
therefore numbers of electrons constituting 1c of charge. n=1c/1.6x10^-19c. =6.25x10^18
