Have you ever noticed how hot your electronic devices get after prolonged use? In this video from the Detailed Engineering channel, we will unravel the mystery behind this phenomenon! The high temperature in cell phones, TVs, chargers and even fluorescent lamps has a fascinating scientific explanation.
When turning on a device, electrical energy causes electrons to move through metals and semiconductors, colliding with ions in the material. These collisions transfer energy, causing the ions to vibrate more intensely, which increases the temperature of the device. It's like an invisible dance inside the device!
But why do even devices with low currents get so hot? This occurs due to energy losses in electronic components. Resistors, capacitors and transistors can dissipate energy in the form of heat, resulting in an increase in temperature, even with low electrical current.
You might think, why not use the best conductors like copper and gold to reduce heat? Although they are excellent conductors, these materials are expensive and can make electronic devices more expensive. Additionally, some cheaper materials, such as aluminum, are also effective and more affordable for manufacturers.
In this video, we'll dive into the nuances of the physics behind heating in electronics and explore how materials efficiency affects temperature. Discover how device design and operating environment also influence heating.

TOOP explicação !!!!

[@paolorodriguez6294]

Obrigado pela explicação.

[@leonardoborges448]

Bom

[@igorfelipe4600]

Meu carregador de celular do aliexpress pega fogo quando eu uso 2 USBs nele ao msm tempo!

[@Vinicius_maia80]

Mas tu usar ainda kkkk

[@ellenhayclen5872]

O que esquenta aqui é o receptor digital de parabólica, o bicho é pequeno mas esquenta muito, isso diminui a vida útil do aparelho. O pior que ele é todo lacrado, aí tive que fazer pequenos furos para ventilação. Kkkk

[@lukegnon]

Na verdade os circuitos eletrônicos esquentam por causa da comutação dos transistores e da alta frequência de operação que por efeito pelicular geram calor.
Os dispositivos também utilizam transformadores, que devido as correntes parasitas geram dissipação de calor
Outro ponto é formação de harmônicos na rede elétrica justamente por causa dos dispositivos eletrônicos

[@nayvosmedia]

Exatamente! Sem os semicondutores atuando como chaves, a eletrônica digital ainda estaria engatinhando e a informática ainda estaria no tempo das válvulas e relés
Falow!!!

É possível fabricar ouro?
