How often should one upgrade or buy a new computer system?

Computer system

In this article, I will discuss some important keynotes about how often should one upgrade or completely buy a new computer system. I want to highlight some keynotes on this topic because it becomes necessary today to understand the value of electronics, ways to minimize the unnecessary buying of newer components. Let’s start from the […]

How to calculate Power Factor?

In electrical engineering, the Power Factor (PF) is a ratio of the real power measured in watts absorbed by the load to the apparent power measured in volt-ampere flowing in the AC (alternate current) circuit. Power factor is a dimensionless number in the closed interval of -1 to 1, this means the value will always […]

What is the difference between an inverter and a UPS?

Inverters and UPS are used to eliminate any blackout due to electricity shorted. Most of us call both the technology one and the same because of its job of restoring the electricity. But there are many differences to compare both. Here is a complete comparison table. Features Inverter UPS Backup The backup of an inverter […]

AWG to MM2

The electrical engineer makes a lot of calculations. Sometimes when an engineer visits a different country and his calculation may differ to a new country. Thus, here is a list of cross-reference AWG (American Wire Gauge) to mm2 (Square Millimeter). Cross-reference AWG to MM2 chart. AWG mm2 30 AWG 0.05 mm2 28 AWG 0.08 mm2 […]

Safety precautions when working with electricity

Cables and wires

Electricity, as useful it is, can be a like-taker as well. Yes, in today’s time, the wire manufacturing companies have enhanced their safety precautions, and now we have access to PV coat wire which is completely safe for high currents (used widely on solar installations) and secure to use. But no matter how safe your […]
