## Both the winding connection is employed in t three phase motor and transformer because of their specific advantages. In case of star star delta starter the stator winding of the motor is first connected to the star connection and then in the delta connection, the reason behind doing so, the star winding has reduced winding voltage compared to the line voltage , which helps to reduce the starting current taken by the motor but the motor is shifted to delta in running condition to provide full load voltage to the armature and to develop rated torque. The distribution transformer are mostly provided with Dyn type of winding, that means it takes input with the delta winding ( the transmission end) and supplies the load with the star winding. This is done due to the reason that the delta winding has effective noise cancellation properties and the star winding can provide neutral point to supply single phase load.

### Ohms law calculator | Calculate Voltage power Resistance and Current

What is ohms law calculator (online): It is basically a calculator based on the principle of ohm's law. You can calculate the third parameter of any dc circuit , if the other two parameter a circuit is known to you.

(Go to the bottom to take part in the ohm's law Top 10 mcq quiz)

The three main parameters are Voltage (V) , Current(I) and Resistance (R). And the relation between them is V=I*R.

Here in this calculator you can additionally calculate the 4'th most important  parameter of any circuit, that is power (P).
