For the same amount of power, a star or delta connection will use the same line current. However a delta connection supplies sqrt(3) times less current to the device on each of its connections because the voltage is sqrt(3) times more.
The apparent contradiction comes about because in a delta connection each connection to the line is shared between two connections to the device (Historikeren 20-07-2015).

What type of connection produce high current?
A device with a low resistive load will produce a high current in a series circuit.
What is star dalta connection?
star delta connection is used reduce high starting current of the motor. you can see the below diagram if you need anything more details... let me know
What is an unintended high-current closed connection between two points in a circuit called?
short or short circuit
Why do we use star to star connection in motor?
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.
When does a motor draw current more than its rated current?
This is a good indication that the motor is being overloaded. If the motor load is belt driven, remove the belt and then check the motor amps. If it goes back to normal FLA then there is a problem with the driven load. If the motor amperage stays high check the motor bearings for the problem.
What would be the cause of high current starter draw?
decribe two causes of higher than normal starter current draw
What type of connection produce high current?
A device with a low resistive load will produce a high current in a series circuit.
What type of series connection will produce a high current?
A device with a low resistive load will produce a high current in a series circuit.
What cause battery positive terminal to melt?
There are two related causes for any connection to melt. The resistance of the connection was high causing excess heat OR The Power draw was to high for the connection. In your case either the connection was dirty or there was short further down the wire.
What is an unintended high-current closed connection between two points in a called?
a short
Unintended high current closed connection between two points in a circuit?
A short, or short circuit.
What is an unintended high current closed connection between two points in a circuit called?
Power Surge
Why would the blower motor on your 2000 Cherokee operate intermittantly and sometimes not at all no matter what the speed is set at?
A loose connection at the motor and/or bad ground at the blower motor. If it is getting current then the motor may have a bad spot/ high amp draw and need to be replaced.
What is an unintended high current closed connection called?
Sounds like an electrical short to me. Officially called a "Short Circut or S/C," these pertain to more than just high-current closed connections.
What is the reason of when electric drill draw high current?
When an electric drill draws high current, it is typically due to increased resistance in the drill bit or the material being drilled. This resistance causes the motor to work harder to maintain the desired speed, resulting in higher current draw. It can also be caused by a dull or inappropriate drill bit, which requires more power to penetrate the material.
Why use star delta gether for motor?
In a large power motor the starting current is too high if connected 'direct on line'. If you start a motor on 'star' connection it uses less current to get it going before the 'delta' connection takes over.
What is star dalta connection?
star delta connection is used reduce high starting current of the motor. you can see the below diagram if you need anything more details... let me know
