If electrical energy costs 12 cents, or $0.12, per kilowatt-hour, how much does it cost to operate an electric over for 5.0 h if it carries a current of 20.0 A at 220 V?

a metal sample carrying a current along X-axis with density Jx is subjected to a magnetis field Bz(along z-axis). the electric field Ey developed along Y-axis is directly proportional to Jx as well as Bz. the constant of propotionality has SI unit. 1. m²/As 2. m²/A 3...
