Electrical circuit Diagnosis - Course 6232-1A circuit is a complete path for current when voltage is applied. Thereare three basic types of Circuits : Series Parallel Series-parallelAll Circuits require the same basic components: Power source Protection device Conductors Load Control device GroundComponentsof a CircuitAll Circuits have thesebasic 2-01TL623f201 Section 2 Electrical CircuitsTypes of CircuitsSection 22-2 TOYOTA Technical TrainingPower source - In automotive Circuits , the source is typically device - Circuits require protection from excessivecurrent. Excessive current generates heat and can damage wires,connectors, and components. Fuses, fusible links, and circuit breakersprotect Circuits by opening the circuit path when there is too - The load can be any component that uses electricity to do work: Light Coil MotorControl device - The simplest control device is a switch.
Section 2 2-4 TOYOTA Technical Training You can use Ohm’s Law to predict the behavior of electricity in a circuit. For series circuits, apply Ohm’s Law as follows: •Total circuit resistance (RT) equals the sum of the individual load resistances (R1 + R2).-RT = R1 + R2 •Circuit current (I) equals voltage (E) divided by total resistance (R).
