So this device measures the current flow in ampere is named as an ammeter or ampere meter. The internal resistance of this device is 0 however in practical; it has some amount of internal resistance. The measuring range of this device mainly depends on the resistance value. The ammeter diagram is shown below.
What is an ammeter explain?
Ammeter, instrument for measuring either direct or alternating electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the major portion.
What is ammeter short answer?
Definition: The meter uses for measuring the current is known as the ammeter. The current is the flow of electrons whose unit is ampere. Hence the instrument which measures the flows of current in ampere is known as ampere meter or ammeter. The ideal ammeter has zero internal resistance.
What is ammeter Class 10?
An ammeter is a device (instrument) used for measuring large electric currents in circuits. For this purpose, it is put in series with the circuit in which the current is to be measured. For accurate measurement, an ammeter must have following two properties: A very small resistance (zero in ideal case).
What is resistor class 10th?
A resistor is an element or component which reduces the electrical current and supply the electricity to the electrical or electronic goods in a controlled manner.
What is voltmeter for class 10th?
Voltmeter is a device in which a large resistance is connected in series with a galvanometer. Voltmeters always connect in parallel in circuits because its resistance is very large. Voltmeter tells us the voltage difference between two points in the circuit.
Where is an ammeter used?
An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
What is A very sensitive ammeter called?
Picoammeter. A picoammeter, or pico ammeter, measures very low electric current, usually from the picoampere range at the lower end to the milliampere range at the upper end. Picoammeters are used where the current being measured is below the limits of sensitivity of other devices, such as multimeters.
What is voltmeter and its types?
The DC voltmeter measures the DC voltage, but the AC voltmeter measures the AC voltage. The DC voltmeter measures the peak value of DC voltage, but the AC voltmeter measures the RMS value of the AC voltage.
What is rheostat class 10th?
Rheostat is an electric device used as a variable resistance, like the regulator of the fan. It is used to change the electric resistance in the electric circuit. UsuallyRheostat consists of a coil of wire with a terminal at one end and a sliding contact that moves along the coil to tap off the current.
What is called resistor?
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
Amps = Watts / Volts 4160 Watts / 208 Volts = 20 Amps. 3600 Watts / 240 Volts = 15 Amps.
