In star each phase is 120 degree apart in delta angle between phases(R,Y,B) are 60 degree so star connection draw low current.
In a high voltage installation, with the same power, current drawn is small compared to those in low voltage. However it requires a thicker insulation, thus cost of insulation is significant compared to the conductor cost. By using a star connected winding, the insulation voltage required is equal to line to neutral connection, otherwise if it is connected in delta the insulation rating has to be provided for a line to line connection. Despite having a higher current, the total cost is still lower compared to using a higher insulation rating.
A device with a low resistive load will produce a high current in a series circuit.

A device with a low resistive load will produce a high current in a series circuit.
A short curcuit is a low-resistance connection established by accident or intention between two points in an electric circuit.
No effect. PF is determined by the load reactance, not current draw. The PT reading should remain essentially unchanged. The CT reading will reflect the lower current draw, and the metering device will simply integrate (correctly) a lower KW.
A low-resistance connection between two points in an electric circuit that forms an alternative path for a portion of the current. Also called bypass. Conductance of a shunt is high as the resistance is low.
Often CFLs are marked with the current. If not, find out the watts and the volts. Divide the watts by the volts to find the current, then double the current because the power factor could be as low as 0.5 with CFLs. That will tell you a safe value to use for the current when planning the wiring.
To provide a low-resistance return in the event of a earth-fault current occurring anywhere in the circuit. The requirement for a low-resistance return is to ensure the resulting fault current causes the relevant protective device to disconnect the faulty circuit.
Higher capacity (higher KW rating) motors take huge starting current to get over the starting torque. To avoid the high inrush of current, star delta starter is used. When started, the motor gets connected in star for few seconds and switches over to Delta and continues to run in delta. In this case motor is designed to run in Delta.
The connection bar is low because your connection strenght is weak, but i don't know why you can't still download songs The connection bar is low because your connection strenght is weak, but i don't know why you can't still download songs
most likely it will be low if you use wirless connection but if you are using wire then your connection is bad.
