Inductive Ammeters do not make physical contact with the circuit, but measure the strength of the magnetic field surrounding the wire carrying the current and measures the strength of the magnetic field that surrounds any conductor carrying a current.
This means that the meter probe surrounds the wire(s) carrying the current and measures the strength of the magnetic field that surrounds any conductor carrying a current.

What is working principle?
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
What is Working principle of venturi tube?
Venturi tube is used to for flow measurement. It work on the principle of Bernoulli Equation.
What is commercial power factor?
Electrical inductive motors, transformers and magnetic ballasts bring real power that are measured in kilowats and reactive power (measured in kilovolt-amperes reactive, kvar). Real power genrates "productive" work. Reactive power does the the magnetic field required for inductive devices to operate.
When dc voltage is supplied to the primary coil of the transformer then the voltage be induced in secondary or not?
The windings of a transformer have both resistance and inductance. When you apply an AC voltage to the primary winding, the opposition to current flow is a combination of resistance and inductive reactance; although the resistance of the winding is relatively low, its inductive reactance is high. The resulting impedance (the vector sum of resistance and inductive reactance) will, therefore, be high and the resulting current will be low.If, on the other hand, you applied a DC voltage to the winding, the only opposition will be the low resistance of the winding. So, if the value of DC voltage is roughly the same as the rated AC voltage, a large value of current would result -high enough to probably burn out the winding.Since transformers work on the principle of mutual induction, a fluctuating magnetic field is necessary to induce a voltage into the secondary winding. Since a fluctuating magnetic field requires a fluctuating current, a transformer will only work if an AC voltage is applied to its primary winding.So, not only will a transformer not work when a DC voltage is applied to its primary winding, it will probably burn out the primary winding.
What is the principle and working of clevenger apparatus?
three fosters control the work of clevenger: boiling temperature of the distillator density and hydrophobic ability.
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.
What are the Principles on which inductive transducer work?
Inductive transducers operate on the principle of electromagnetic induction, where a change in magnetic flux induces an electromotive force (EMF) in a coil. They typically consist of a coil and a ferromagnetic core, where the movement or variation of the core affects the inductance of the coil. As the inductance changes due to displacement or other physical parameters, it produces a corresponding change in the output voltage, which can be measured and converted to represent the desired variable. This principle allows inductive transducers to effectively convert mechanical motion into electrical signals.
Will an inductor work on DC?
An inductor cannot work in dc because the frequency is zero there by making the inductive reactance zero as a consequenceAnswerOf course an inductor can work in a d.c. circuit!
Does an pure inductive load work in dc supply?
no
Why inductive sensor work mainly on metal?
An inductive sensor depends on ferro-magnetism, which is a characteristic of certain metals, such as iron.
Does it matter where you place an ammeter in a circuit?
Ammeters must always be placed in series in a circuit, otherwise they will not work babes :)
Example of inductive order?
Inductive order is starting from the bottom and working upward. Examples works of inductive order start with specific details of the event and work back to a more broad scenario.
Inductive reasoning and deductive reasoning?
Deductive reasoning is when researchers work from general information to more specific information. Inductive reasoning is when researchers work from specific observations to theories and generalizations.
What is zero power factor?
A power factor equal to zero means that the load is purely inductive or purely capacitive, and no power is available to do work, because all of the generated power is going into charging the electric field in the capacitor, or the magnetic field (if an inductive load).
Whose scientific work relied on observation experiments and inductive reasoning?

What is the working principle?

How does an inductive dwell tach work?
