Cloud computing is an application-based software infrastructure that stores data on remote servers, which can be accessed through the internet. To understand how cloud computing works, it can be divided into front-end and backend.
The front-end enables a user to access data stored in the cloud using an internet browser or a cloud computing software. However, the primary component of cloud computing – responsible for securely storing data and information – is the backend. It comprises servers, computers, databases, and central servers.
The central server facilitates operations by following a set of rules known as protocols. It uses a software, middleware, to ensure seamless connectivity between devices/computers linked via cloud computing. Cloud computing service providers usually maintain multiple copies of the data to mitigate instances of security threats, data loss, data breach, etc.

Considerando a relação de transformação, onde a corrente no primário é de 800 A e com uma relação de espiras de 1/160, a corrente no secundário corresponde a:
Fonte: Creder, Hélio, Instalações elétricas
Após análise do circuito, a corrente que flui pelo resistor corresponde a:
Quando alimentado por uma fonte de tensão de 220 volts, valor eficaz, a corrente que circulará pelo circuito correspondente a:
A primeira lei de OHM relaciona três grandezas fundamentais, a saber:
A ação de elaborar o layout de placas requer escolher a melhor configuração de aproveitamento do espaço físico e alocação correta dos dispositivos eletrônicos na posição projetada. Há no mercado alguns softwares para tal objetivo. A figura mostra um exemplo.

Para ter bom layout, o projetista precisa:
Capacitores podem ser associados em série, paralelo, ou em uma combinação série/paralela.
Os diagramas a seguir ilustram quatro combinações com três capacitores de 120 nF cada, ligados aos pontos M e N.
(1) 
(2) 
(3) 
(4) 
A associação de capacitores que apresenta capacitância equivalente de 180 nF corresponde ao diagrama:
Com base no circuito, a resistência e tensão equivalentes de Thevenin, RTH e Vth nos pontos A e B são:
Portanto, um motor com resistência interna de 1 ohm, acionado por 380 volts de tensão e 10 ampères de corrente, terá uma fem de:
