circuit a path for electric current
closed circuit a complete, unbroken path for electric current
electric current movement of electrons from one place to another
open circuit an incomplete or broken path for electric current
static electricity buildup of electrical charges
conductor material through which electricity passes easily
insulator material through which electricity does not pass easily
resistance measure of how easily electric current will flow through a material
alternating current current that changes direction regularly
direct current current that flows in one direction
dry-cell battery electric power source with a dry or paste-like center
electromotive force the push that keeps the current (electrons) flowing in an electric circuit
terminal points where electrons leave or enter a battery
volt the metric unit used to measure electromotive force that tells the amount of push
voltage the energy that a power source gives to electrons in a circuit
wet-cell battery electric power source with a liquid center
series circuit a circuit in which all current (electrons)flows through a single path
ohm's law current equals voltage divided by resistance
