18.1 questions and answers 2023 verifiedschematic diagram representation of a circuit that uses lines to represent wires and different symbols to represent components the filament of a light bulb acts as a resistor when a wire connects the terminal of a battery to a light bulb, charges that have built up on one terminal of the battery have a path to follow to reach the opposite charges on the other terminal because there are charges moving though the wire, a current exists and caused the filament to hear up and glow together the bulb, battery, switch, and wire form an electric circuit- path through which charges can flow an electric circuit is a set of electrical components connected such that they provide one or more complete paths for the movement of charges a schematic diagram for a circuit is sometimes called a circuit diagram load any element or group of elements in a circuit diagram that convert electrical energy to other forms of energy a simple circuit consists of a source of potential difference and electrical energy (such as a battery) and a load (such as a light bulb) because the connecting wire and switch have negligible resistance, we do not consider these as part of the load. (In a wire, there is very little electric energy that is converted to heat energy) closed circuit a circuit which contains a complete path for electrons to follow open circuit without a complete path, there is no charge flow and therefore no current (situation called) a switch in a circuit must be _____ in order for a steady current to exist closed if the switch was open, the current could not flow through the switch but would instead be stopped. This created an open circuit and the bulb would not light up short circuit closed circuit that does not contain a load. can be hazardous without a load (such as a bulb or other resistor) the circuit contains little resistance to the movement of charges
