why ammeter is connected in series with the circuit?
203001
An ammeter measures the electric current in a circuit. The name is derived from the name for the SI unit for electric current, amperes (A). In order for an ammeter to measure a device's current, it must be connected in series to that device. This is necessary because objects in series experience the same current.

A series circuit is one that has more than one resistor, but only one path through which the electricity (electrons) flows. From one end of the cell (battery), the electrons move along one path with NO branches, through the resistors, to the other end of the cell.

An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit. We will find the shunt as part of the ammeter circuit. The "shunt" is nothing more than a resistor with a very low resistance.

The voltmeter is connected in parallel with the circuit to be measured. We do not want the voltmeter to load the circuit. Consequently an ideal voltmeter will have infinite resistance. An ammeter is connected in series with the circuit to be measured.

The amount of current in a series circuit is the same through any component in the circuit. This is because there is only one path for current flow in a series circuit.

All multimeters have voltage and current meters (otherwise they'd just be called voltmeters and ammeters!), and most also measure resistance. There are a variety of other "extra" features depending on manufacturer and cost (e.g. continuity, capacitance, frequency, etc.).

Most multimeters inherently measure voltage, and pass a current to be measured through a shunt resistance, measuring the voltage developed across it. The voltage drop is known as the burden voltage, specified in volts per ampere. ... The burden voltage can be significant in very low-voltage circuit areas.

A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors: ... I = V / R = 10 / 20 = 0.5 A.

The electronic voltmeter gives the accurate reading because of high input resistance. The moving coil voltmeter is not able to detect the low voltages.

Series circuits All mains operated appliances have switches that are connected to the live wire (the wire that carries current into the appliance). When a switch is in series with a device, it controls the device, allowing us to switch it on and off.

Key Points A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. An ammeter is a measuring device used to measure the electric current in a circuit.

In a series connection, the current flowing through all the components of the circuit is the same. Ammeter aims at measuring the current in the circuit, hence it is connected in series so that the same current that is there in the circuit flows through it and gets measured.

Because in a parallel circuit voltage is everywhere the same. The lights, as well as appliances, etc. need the full source voltage in order to operate properly. A series connected circuit divides the voltage based upon the resistance of the load.

The electric current in one part of a circuit is measured with an ammeter, which gives a reading in ampere. To take the measurement, a gap is made in the circuit and the ammeter is connected into that gap, so that the charged particles moving around the circuit must pass through the meter.

A DC ammeter is thus sensitive to which way round it is connected; most are marked with a positive terminal. A moving coil meter indicates the average (mean) of a varying current through it, which is zero for AC. For this reason moving-coil meters are only usable directly for DC, not AC.

A galvanometer can detect only small currents. Thus, to measure large currents it is converted into an ammeter. It can be converted into an ammeter by connecting a low resistance called shunt resistance in parallel to the galvanometer.

This is an RLC circuit, which is an oscillating circuit consisting of a resistor, capacitor, and inductor connected in series. ... The voltage in the capacitor eventually causes the current flow to stop and then flow in the opposite direction. The result is an oscillation, or resonance.
