The scientists are going to show us how electrical energy flows around an electrical circuit. Title: Circuit symbols This is what a battery looks like as a circuit symbol. Electricity can travel ...

Hydraulic circuits are comprised of cylinders, valves, pumps, and are connected via hydraulic pipes and tubes. The complexity of these components are difficult to represent fully so hydraulic symbol ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
