This quantity is equal to
This quantity is equal to the line integral of the electric field, and on a Josephson junction made of two superconductors coupled by a weak link, current flows indefinitely without this quantity being applied. At the tip of an antenna, this quantity becomes extremely high, which is caused by the impedance approaching infinity. The electric field is perpendicular to the contour lines of this quantity, and around a closed loop, the sum of this quantity is equal to zero. This quantity is known as electromotive force when produced by a battery. For 10 points, name this quantity which, according to Ohm's Law, is equal to current times resistance.
