A circuit is a closed loop containing various components. Electrical current flows around the circuit. Scientists use symbols to represent the different components in a circuit. Symbols are simplified ...

An electrical schematic diagram might look like a nonsensical drawing to the layman, but to the electrical engineer, it’s a high-level documentation that provides a ton of insight and instruction. The ...

A circuit always has a battery (cell) but it can also contain other electrical components, such as bulbs, buzzers and motors. When drawing circuit diagrams, rather than drawing detailed components, we ...

Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate ...

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 ...
