a) Ideal conductor b) Ideal voltage source c) Ideal current source d) Short circuit e) Open circuit

Work Step by Step

a) An ideal conductor is a straight line that has no breaks in it. This indicates that there is no resistance across the conductor. (The most common thing that this represents is a wire, although it can apply to any ideal conductor.) b) An ideal voltage source is one in which no voltage is lost over time. After all, with actual batteries, their efficiency and their voltage decline over time. With ideal voltage sources, however, the voltage remains constant over time. c) Like an ideal voltage source, an ideal current source maintains a constant current source that does not decline over time. d) A short circuit is a circuit in which electrons can return to the battery without going through a resistor. This is extremely dangerous and can cause a battery to explode. e) An open circuit is a circuit with a break in the circuit that prevents there from being a complete loop that goes through the circuit elements and the battery. This prevents electrons from flowing.
