What else can I help you with?
Why does a capacitor keep its charge after the supply is disconnected?
Yes, it can. Then you can use the charge to power something else. :)
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
What cable size to use for a 1 kw motor for a 400v 50 hz 3 phase supply?
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
What happen when single phase supply of induction motor interrupted while driving the load?
That happens when the supply is turned off, and the motor runs down and stops.
Function of switched capacitor for three phase power generation from single phase?
usually they say its possible 2 convert a 2phase supply to 3 phase.if its so then how?
Why don't have 2phase supply?
Two-phase supplies, in which the phase voltages are displaced from each other by 90 degrees, are less economical than three-phase systems.
Why you have to connect DC supply to the induction motor?
To start an induction motor we have to excite field. The excitation is done by connecting the DC supply to the field winding's.
What will happen if inductor connected with DC supply?
i think in case of dc supply there will not be any induction
Why does a capacitor keep its charge after the supply is disconnected?
Yes, it can. Then you can use the charge to power something else. :)
Why is a power supply even after the power supply has been disconnected?
because the power still are in circuit of the motherboard and you have to drain the system
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
How do you use disconnect in a sentence?
Please don't disconnect the electricity supply.
What cable size to use for a 1 kw motor for a 400v 50 hz 3 phase supply?
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
Disadvantages of 3 phase induction motor?
One of the disadvantages of the 3 phase induction motor is that it requires a three wire supply. The other disadvantage is that the 3 phase induction motors have poor starting torque and high have in the rush currents.
What happens if 3 phase supply is given to stator and rotor both in a induction motor?
its impossible to give suppy to rotor of an induction motor,because of it a closed path for circulating currents.
