At resonance, V_L and V_C are in antiphase (i.e. 180⁰ out of phase), therefore, their vector sum can be quite small— zero They are equal in magnitude at resonance.

So, they are greater than V in series LCR circuit.

When AC current flows through the coil of an inductive device, eddy currents are set up in its core. The eddy currents have heating effect. If the core is a single piece of metal, its resistance becomes very low and very high eddy current flows through it. This causes excessive heating of the core and may destroy the device. To avoid destruction by heating, the eddy currents are to be greatly reduced. To reduce the eddy currents, the resistance of the core is to be increased significantly for...

The Hall Effect, also called the Hall–Heroult effect, is the influence of the transverse component of an electric current on the magnetic field in a transverse Hall bar. When a current flows in a plane perpendicular to the direction of the magnetic field, the Lorentz force acts on the magnetic charges (magnetic flux) enclosed by the transverse current.

The Lorentz force is the force experienced by a magnetic charge when acted upon by an external force field, which in this case is the...

A transformer relies on the principle of electromagnetic induction, which works with changing magnetic fields. Since direct current (DC) has a constant magnitude and does not change direction, it does not create the varying magnetic field necessary for induction in a transformer. Therefore, transformers are not suitable for altering the value of DC voltage.

The self-inductance of a coil is given by the formula:

L = (μ * N² * A) / l,

where L is the self-inductance, μ is the permeability of free space (constant), N is the number of turns, A is the cross-sectional area of the coil, and l is the length of the coil.

Let's assume the smaller coil has a radius 'r' and the larger coil has a radius '2r' (twice the radius of the smaller coil). Since the number of turns is the same for both coils, let's denote it as 'N' for simplicity.

For the smaller coil:

A =...

The rule used to determine the direction of the current induced in a conductor moving in a perpendicular magnetic field is known as Fleming's right-hand rule. According to this rule:

1. Extend your thumb, index finger, and middle finger of your right hand perpendicular to each other.

2. If the thumb points in the direction of motion of the conductor (conventional current flow), the index finger points in the direction of the magnetic field, then the middle finger will point in the direction of...

Mutual induction is a phenomenon where a changing magnetic field in one coil induces a voltage in a nearby coil. It is utilized in various applications:

1. Transformers: Mutual induction is the basis of transformers, which are used to step up or step down voltages in electrical power transmission and distribution systems.

2. Inductive Coupling: Mutual induction enables wireless power transfer, RFID systems, and near-field communication, where energy or information is transferred between two...

1.Induction Brake Basics: An induction brake, also known as regenerative braking, harnesses the electric motor's ability to act as a generator. When the driver applies the brakes, the electric motor switches its function from propulsion to generation, converting the kinetic energy of the vehicle into electrical energy.

2. Energy Conversion: During induction braking, the rotating wheels drive the motor, causing it to generate electricity. This electrical energy is then fed back into the...
