A measure of the electric charge passing through a metal wire. Electric current is usually given in the units of amperes. One ampere is the flow of one coulomb of electric charge per second. High frequency electric currents has been used to kill wood-boring insects on non-metal containing objects. Low frequency electric currents (2000-3000 volts, 0.5 milliamps) has been used to keep birds from roosting on monuments.
