THINGS YOU WILL NEED Module Electrical project board and accessories DVOM module E C 1 KIA Automotive Electrical Circuit Analysis A circuit is a path for current to flow Electrical behavior in a circuit is influenced by Design of the circuit - Number and types of load devices Size of the conductors ELECTRICAL CIRCUITS The path that electricity flows through is called a circuit. The circuit must form a complete loop from the positive side of the power source to the negative side of the power source. Electrical behavior in a circuit is determined by the design of the circuit the number and types of load devices the size of the conductors and the types of control devices used by the circuit. - Types of control devices EC1-2 Electrical Circuit Components A basic automotive electrical circuit consists of a voltage source battery generator conductors usually wires or the vehicle body and one or more load devices that perform some type of useful work such as lamps motors etc. Most electrical circuits have at least one protection device such as a fuse a circuit breaker or a fusible link and one or more control devices including switches relays and solid-state devices such as transistors.
