How to measure the resistance of three phase motor with triangle connection Is it the outgoing line measurement of phase A and phase B
Measuring the resistance of A-phase and B-phase outgoing lines is the resistance of AB coil and the other two coils in parallel. You can measure three and calculate them again
If it is to see if the motor coil is balanced, just measure three separately to see if they are equal
How much is the current of the series circuit when a 5 Ω resistor R1 is connected in series with a 15 Ω resistor R2 and connected to a 6V power supply?
