What is rated current and maximum current?
The basic rating is continuous current, the value of amperes intended to flow through the device. (This is sometimes described as "operational current" or "thermal current.") When we speak of a "100...

Why dc current is called direct current instead of direct current current?
dc is an abbreviation for direct current. The term dc current is sort of wrong it's a bit like saying something twice for no reason. It might be better to say dc electricity rather than dc current....

What is phase current and line current?
A phase current is the current passing through a phase, whereas a line current is the current flowing through a line. In the case of a balanced delta-connected load, IL = 1.732 IP. In the case of a...

How current transformer measure current?
A current transformer doesn't 'measure current'. It merely reduces a large current flowing through its primary to a smaller current which can be read by an ammeter connected to its secondary. At the...
