... Making a bulb light up A circuit has to be a complete circle. You connect the wire to either side of the battery, the positive and the negative side. Then you put one wire going up one side of the battery and one going up on the other side. So the wires go up on either side of the battery like a ci ...

... In variable-torque applications suited for Volts per Hertz (V/Hz) drive control, AC motor characteristics require that the voltage magnitude of the inverter's output to the motor be adjusted to match the required load torque in a linear V/Hz relationship. For example, for 460 volt, 60 Hz motors this ...
