How to Read Electrical Schematics

Power sources supply electrical energy to a circuit in the form of voltage and current. Every functional electronic circuit needs to have a DC or AC power source. DC Power Sources. Direct current (DC) power sources provide electric current that flows in a constant direction. This is the schematic symbol for a DC power source:

How to Use a Multimeter to Measure Current

Current is measured in amperes, abbreviated as "A". Voltage is measured across the terminals of the power source (just as measuring the height of the overhead tank). Current is measured inside the circuit (similar to measuring water with a flow meter). Current is measured using an ammeter, which is included in a multimeter.

Fundamentals of Rectifier Operation, Monitoring, and Maintenance

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. It is imperative that a rectifier remain in a state of constant operation. Because a rectifier is an electrical device, it is vulnerable to power surges.

Understanding Battery Polarity: The Key To Electrical Flow

Battery polarity refers to the distinction between its positive and negative terminals, crucial for proper and safe usage. The positive terminal has higher electrical potential, while the negative terminal has lower, creating a voltage difference between them. This voltage difference drives an electrical current from the positive to the negative terminal. Understanding …
