Resistors, Electromotive Force and Power Dissipation
https://www.electronics-lab.com/article/resistors-electromotive-force-and-power-dissipation/
Resistors A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. It is a conductor that impedes the flow of electric charge through it, creating electrical resistance. Such resistance results from collisions between free electrons and the crystal lattice of the conductor’s atoms. This is the main property of resistors. […]

Power Meter gives accurate Measurement For energy Consumption of IoT devices
https://www.electronics-lab.com/power-meter-gives-accurate-measurement-energy-consumption-iot-devices/
In the world of today’s technology, the Internet of Things is very popular. We see that most of the devices used to create the IoT (Internet of Things) function on small batteries or energy harvesting. We find it quite hard measuring the amount of energy being consumed by these IoT devices due to the dynamic […]
Power-handling capabilities of inductors
https://www.electronics-lab.com/power-handling-capabilities-inductors/
App note from Coilcraft on how to calculate the power dissipation of an inductor. Inductors are not typically rated by power, however an approximation of the power-handling capability of an air core or ceramic core chip inductor can be estimated using the data sheet specifications for current and resistance. Power-handling capabilities of inductors – [PDF]
