Question

voltmeter is connected in parallel and ammeter in series why not vice versa explain it plz

Answer 1

the resistance may go to zero and the instrument may burn

Answer 2

Voltage means Potential difference between two points.V=IR ( ohms law)In order to measure the voltage ,voltmeter should be connected in parallel. Voltmeter provides very high resistance .When voltmeter connected in parallel ..so no current flowing through it due to very high resistance.. Voltage drop will occur..we get some voltage so its indicates voltage ( as per definition).Now if it is connected in series..then due to high resistance no current will flow through circuit..so no voltage drop occur. Voltage in same line is zero..its indicates zero.So, voltmeter is always connected in parallel.Current means flow of charge (free electrons) in define direction.I =Q/tCurrent is measured by Ammeter.Ammeter has very low resistance.Ammeter is connected in series ..more amount of current flow through it due to low resistance..it act like closed switch..so it indicates the current.Now, Ammeter is connected in parallel..due to low resistance act like short circuit..chances of ammeter get damaged.So, Ammeter is always connected on series.
