Chapter 16, Problem 1SA
How will an electrical circuit behave if there is a short in the circuit?
Expert Solution & Answer
To determine
The behaviour of an electric circuit, if there is any short in it.
Explanation of Solution
The short circuits were also referred as low resistance circuits. If there is any short existing in the circuit, it causes unparallel legs or a path to be built into the circuit. These unintended paths increase the flow of current into the circuit. Due to this high current, the circuit becomes uncontrollable and can damage the entire electrical system of the vehicle. The reasons for occurring shorts in the electrical system is perhaps due to loose wire connection, damaged wires insulation, and improper wiring or careless installation of accessories.
