Answer Posted / engr khan
AC Resistance
In Simple words, Resistance in AC circuits is called
Impedance. Or
The Overall resistance (Resistance, Inductive reactance and
Capacitive reactance) in AC circuits is called Impedance (Z).
DC Resistance
We know that there is no concept of Inductive and Coactive
reactances in DC Circuits. i.e. capacitive and inductive
reactances in DC circuits zero because there is no
frequency in DC circuits, i.e. magnitude of DC current is
constant. Therefore, only the original resistance of wire
comes into play.

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
