The susceptibility of −4.2 × 10-⁶ indicates that the material is diamagnetic. Diamagnetic materials have a small negative susceptibility, meaning they are weakly repelled by a magnetic field and do not retain magnetism.

The reactance offered by a capacitor decreases with increasing frequency because reactance (XC) is inversely proportional to the frequency of the alternating voltage, as given by the formula XC = 1/2πfC, where f is the frequency and C is the capacitance.

The reactance offered by a capacitor decreases with increasing frequency because reactance (XC) is inversely proportional to the frequency of the alternating voltage, as given by the formula XC = 1/2πfC, where f is the frequency and C is the capacitance. As the frequency increases, the rate of change of voltage across the capacitor becomes faster, allowing it to charge and discharge more rapidly, reducing the opposition to current flow.
The underlying principle of a transformer is electromagnetic induction, based on Faraday’s law of induction. When an alternating current flows through the primary winding, it creates a changing magnetic flux in the core. This flux induces a voltage in the secondary winding, proportional to the turnsRead more
The underlying principle of a transformer is electromagnetic induction, based on Faraday’s law of induction. When an alternating current flows through the primary winding, it creates a changing magnetic flux in the core. This flux induces a voltage in the secondary winding, proportional to the turns ratio of the primary to secondary windings. The energy transfer occurs without physical contact between the windings, relying entirely on the magnetic field.
Large-scale transmission of electric energy over long distances is achieved using transformers. At power plants, step-up transformers increase the voltage, which reduces the current and minimizes transmission losses. High-voltage electricity then travels efficiently through transmission lines.

Large-scale transmission of electric energy over long distances is achieved using transformers. At power plants, step-up transformers increase the voltage, which reduces the current and minimizes transmission losses. High-voltage electricity then travels efficiently through transmission lines. At distribution points, step-down transformers lower the voltage to safe, usable levels for consumers. This process ensures that electricity is transmitted economically and efficiently over vast distances, reducing energy loss and making it suitable for everyday use.
