A superconductor is a material that, below a certain critical temperature, has the ability to conduct electricity without any resistance. In addition, it exhibits the phenomenon of perfect diamagnetism, which means it expels all magnetic fields from within the material (known as the Meissner effect).
Therefore, a superconductor exhibits diamagnetism, which is a characteristic of materials that weakly repel magnetic fields.
Final Answer: Dia magnetism
An inductor and a resistor are connected in series to an AC source of voltage \( 144\sin(100\pi t + \frac{\pi}{2}) \) volts. If the current in the circuit is \( 6\sin(100\pi t + \frac{\pi}{2}) \) amperes, then the resistance of the resistor is:
