What else can I help you with?
Can you use ac ammeter to measure dc current?
It depends. If it's an inductive ammeter (the kind that clamps around a wire), it won't work at all. If it is the type of ammeter that is actually placed in the circuit, it will work but it won't be accurate.CommentActually, modern 'clamp on' ammeters WILL measure d.c. currents. It uses the Hall Effect to measure the current.
Is an ammeter found on a series or parallel circuit?
Series. An ammeter is used to measure current, and is connected in series! There are also clamp on ammeters that use a small current transformer that is placed around a wire in the current loop in question. A small amount of current will be induced on this wire which can be read by the meter. This is not exactly in series or in parallel, but it "steals" some power from the circuit to induce in the meter, and at the same time keeps the circuit intact.
The current in a wire is determined by what?
an ammeter can be used to measure current flow, either direct insertion type, where the circuit must be opened and the meter is inserted in series with the load, or a clamp on type.
What measurement can vary with AC current by not DC current?
HZ. Hertz is the name given to the frequency of the alternating circuit. Direct current (DC) has no frequency since one wire is always positive and the other is always negative; but AC (Alternating Current) rapidly changes polarity, and does so at a rate that is defined by HZ.
Which type of current invovles flow of charge in two directions?
A direct current involves change of flow in a single direction. DC (direct current), at least on the macro scale. On the atomic scale, they seem to wander all over the place between atoms, and the average movement is what we measure as current.
What are the kinds of ammeter?
The ammeter is a device that measures the electric current. Hot wire, electrostatic, moving iron, moving coil, and induction are the kinds of ammeter.
What does a inductive ammeter do?
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is typically measured using an ammeter, which is connected in series with the wire. The ammeter measures the flow of electrons in the wire and displays the current in units of amperes (A). Make sure to set the ammeter to the appropriate range before taking the measurement.
Why ammeter connects in series and voltmeter in parallel in electric circuit?
Because the ammeter measures the current flowing THROUGH the wire, butthe voltmeter only measures the potential difference between two points.
Why ammeter use fuses and volt meter do not?
An ammeter measures current THROUGH a circuit, a voltmeter measures current ACROSS a circuit. The ammeter is connected to a power source in series, essentially actually becoming part of the circuit. The current is flowing directly through the ammeter as if there were a wire in its place. If there is a surge from a substantial power source, the ammeter would be destroyed and the user could be severely injured. The fuse will "blow" if its "load" is exceeded breaking the circuit. A volt meter is connected to a power source in parallel because it has an extremely high resistance and little to no current would get through. You don't need a fuse because the current doesn't flow through it openly.
Why the windings of an ammeter should be of thick wire?
because lots of current is likely to be flowing through them.however a shunt ammeter is easier to build than the direct ammeter as described above. in a shunt ammeter you use an ordinary meter wound with fine wire and put a small value shunt resistor across it to take almost all the current.
Do amp meters measure power when device on circuit is turned off?
An amp meter measures current flow, not power. An amp meter measures instantaneous current either by being inserted in series with the wire being measured for current flow, or clamped onto a single current carrying wire and measuring current flow by induction. If the load is disconnected then no current will flow and the amp meter will read zero.CommentThe correct term is ammeter, not 'amp meter'.
Moving a magnet in and out of a coil of wire produces?
Moving a magnet in and out of a coil of wire induces an electric current in the wire. This phenomenon is known as electromagnetic induction and is the basis for how generators produce electricity.
What is moved up or down repeatedly through a coil of wire an alternating current is inducted in the wire?
A magnet or magnetic field is moved up or down repeatedly through a coil of wire, inducing an alternating current in the wire through electromagnetic induction.
What instrument measures both ac and DC?
hot wire ammmeter or a moving iron ammeter will work for ac and dc.
An ammeter when connected to wire does not show any value of currentwhy?
If it is an ammeter designed for DC (direct current) like you have in a car and you connect it in an AC (alternating current) circuit (like you have in your home) it will read zero, even though it is obvious that current is flowing.
Loops of wire that turn in the magnetic field of an armature create?
alternating current
