Q: In ferromagnetic materials, a version of this effect occurs in which the resultant resistivity predicted by this effect contains an additional zero-field term proportional to the magnetization. Arranging two solid-state elements which demonstrate this effect at right angles to each other and summing their output voltage to eliminate the noise is a typical way of producing a magnetic field sensor using this effect. This effect is derived by noting that the current crossed with the magnetic field creates a transverse current, which results in a potential difference. For ten points, identify this classical effect in which charge flowing across a transverse magnetic field results in an electric field component orthogonal to both the current and the magnetic field, often used to measure the sign of charge carriers.

Q: The relationship between temperature and this quantity is given by the Steinhart-Hart equation. Tunnel diodes have a negative value for this quantity, whose changes are measured by the most common type of strain gauge. The proximity and skin effects cause increases in this quantity with increasing frequency. The time constant tau is equal to indudctance divided by this quantity in an RL circuit. An unknown value of this quantity can be determined with a Wheatstone bridge. This quantity is the real part of impedance in AC circuits, and it is equal to voltage divided by current. For 10 points, name this opposition to the flow of current that is measured in ohms.

Q: This author's relationship with Lord Alfred Douglas led to his imprisonment on sodomy laws, during which time he penned De Profundis. After his release from prison, he wrote a poem containing the line "Yet each man kills the thing he loves", The Ballad of Reading Gaol. This author of An Ideal Husband and Lady Windemere's Fan wrote one play in which Gwendolyn Fairfax loves the title character in part due to his name and in his only novel, this author describes the title character's destruction of a painting done by Basil Hallward. For 10 points, identify this Irish writer of The Importance of Being Earnest and The Picture of Dorian Gray.
