What is meant by bifilar?
1 : involving two threads or wires bifilar suspension of a pendulum. 2 : involving a single thread or wire doubled back upon itself a bifilar resistor.
How does a bifilar coil work?
One wire is clamped to ground usually by a diode so that when the other “primary” wire of the bifilar coil no longer has a voltage applied across it by the switching transistor, the stray magnetic flux generates a current in the clamping coil with the primary side voltage appearing across it, causing an equal voltage …
How a bifilar pendulum works?
Apparatus : A rectangular metal or wooden block having a pair of chucks or hooks on each of its three planes(bifilar pendulum) . When the body is twisted through a small angle in the horizontal plane and released, it executes simple angular oscillations about the vertical axis passing through its centre of gravity.
What is a bifilar transformer?
A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for transformers.
What is the advantage of a bifilar winding?
Bifilar Coils (with opposing windings) The opposing currents create an overall canceling effect, thus no major external field is produced. A bifilar coil will produce almost no inductance to a changing, or AC current. This makes them useful for creating non-inductive wire wound resistors.
What type of oscillation does bifilar suspension gives?
angular oscillations
The body is suspended from a rigid support MN by means of a equal and torsion less string. When the body is twisted through a small angle in the horizontal plane and released, it executes simple angular oscillations about the vertical axis passing through its centre of gravity.
How is the bifilar suspension used in physics?
INTRODUCTION. The bifilar suspension is a technique used to determine the moment of inertia of any type of object about any point on the object. This is done by suspending two parallel cords of equal length through the object examined. However, the approach taken for this experiment is to determine the moment of inertia
What is the meaning of the word bifilar?
Definition of bifilar. 1 : involving two threads or wires bifilar suspension of a pendulum. 2 : involving a single thread or wire doubled back upon itself a bifilar resistor.
How is the radius of gyration determined by bifilar suspension?
The bifilar suspension technique offers the opportunity to determine the radius of gyration of a body by relating the readings gotten from the procedure in the techniques and relating that into the equation of angular and this invariably provides the determination of the moment of inertia for the same body. Length of bar l.
Which is the best description of a bifilar pendulum?
Definition of bifilar. 1 : involving two threads or wires bifilar suspension of a pendulum 2 : involving a single thread or wire doubled back upon itself a bifilar resistor.
