Why meter ampere was connected in series and voltmeter was connected in parallel in a circuit?

An ammeter is used to measure the current through a circuit and thus it must be in series with that load. Also, it's resistance is so low that it cannot be connected in parallel since it will result in a short circuit.
A Voltmeter is intended to measure the voltage across a circuit and thus it must be connected in parallel. It has a very high resistance such that connecting it in series with a circuit will lender the circuit useless or inoperative.

∙ 10y ago-- A voltmeter measures the potential difference between two points.
So the meter must connect to the two points, but it must not change
or disturb anything that's going on betweem them electrically.
-- An ammeter directly measures the current flowing through a conductor.
The only way to directly measure current (at least DC) is to make the current
flow through the meter.

How is an ammeter converted to a voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
What is the charge flowing per second in a circuit?
The numerical representation of one coulomb of charge moving past a point in a circuit per second is called an ampere.
What is the ampere rating of circuit A16?
14
What are the breaker ampere trip ratings?
The ampere frame rating for a circuit breaker designates how the circuit breaker should be configured. It also states the trip unit of the amp.
What is VA burden in electrical engineering?
The term 'burden' is used to describe the secondary load applied to an instrument transformer; the reason for this is so that it is not confused with the 'load' supplied by the high-voltage circuit to which the transformer's primary is connected. A burden is either a measuring instruments (ammeter,voltmeter, wattmeter, etc.) or protective relay, depending on the function of the instrument transformer. 'V.A' is the symbol for 'volt ampere', which defines the 'power' rating of the instrument transformer.

How much current will flow in a circuit with a 12 VDC source connected to a 1K-ohm load?
I = E/R = 12/1,000 = 0.012 ampere = 12 milliamperes.
What are the breaker ampere trip ratings?
The ampere frame rating for a circuit breaker designates how the circuit breaker should be configured. It also states the trip unit of the amp.
How many 100watt 220volts bulbs can be safely used in a circuit with a fuse of 5 ampere rating?
The current (ampere) changes from a high value at switch on to a run current of of approx 0.5 amperes. The fuse blows at switch on if too many lamps are connected. It also depends on the cable used to wire up the lamps and the length of the cable.
