Terminologies
Circuits - composed of electronic components in which electrons can flow
Sensors - detects changes in the environment, stores the info and sends it to other electronic components
Actuators - converts any type of energy (in this topic, electrical energy) into mechanical energy
Transformers - a passive electrical component that transfers electrical energy from one circuit to another ciruit. In AC, transformers lower voltage by increasing current or increases voltage by lowering the current
Circuits
How to solve Impedance, Phase Angle, Reactance using a Calculator
Presumably should use a fx-991ES or fx-570ES Calculator from experience
Circuit Formulas - useful in education
Electrical Engineering Formulas
Kirchoff's Law - Voltage and Current Formulas
AC vs DC
Alternating current (AC) and
Direct Current (DC) are 2 ways to transmit electricity to homes. Learn their difference here.

An alternating current is a current who alternates back and forth through the wires while a DC current is a current whose flow is uni-directional.
