MCB Trip Curves – A, B, C, D, and More
As we all know, MCB (Miniature Circuit Breaker) is a compact electrical switch designed to automatically break and interrupt the flow of electricity in case of over-current or short-circuit, offering protection for circuits and devices in residential as well as commercial applications. But there are different types of miniature circuit breakers for different applications and […]

What is inrush current?
Inrush current, also known as ‘inrush current surge’ or ‘switch-on surge’, refers to the temporary surge of electrical current that occurs when a device or electrical equipment is first turned on. This term is particularly relevant in applications like heavy power systems, transformers, motors, and electronic devices. Why is there inrush current, can’t we do […]

Calculating battery charging current
Calculating the battery charging current involves considering the battery’s capacity (in Ah, ampere-hours) and the desired charging rate or time. You can extract those information from battery or its user manual, if there. The formula to determine the charging current is: Charging Current (in A) = Battery Capacity (in AH) ÷ Charging Time (in hours) […]

Calculating battery charging time
The charging time for a battery or battery bank (lead-acid and lithium-ion) can vary depending on several factors such as the charging current, the state of discharge, and the type of charger being used. As a general rule of thumb, to calculate the approximate charging time for a battery, you can use the formula: Charging […]
