What device can be used to increase current in a DC circuit?
Transformer or instrument transformer. It can increase and decrease current output.
What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
Why induction motor current increase when load increase?
The slip is proportional to the load torque in an induction motor. This can also be seen as a reduction in speed causing extra current to be induced in the rotor to supply the increased torque.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
Current travels from a power plant to a transformer that increases voltage through a what?
circuit
How are the two circuits of an induction motor similar to the circuit of a transformer?
They are magnetically coupled--a current in one circuit induces a current in the other one in both a transformer and an induction motor.
What happens to the rotor speed and rotor current when the mechanical load on an induction motor increases?
rotor speed will decrease....the rotor current wil increase.....

Difference between transformer and induction motor?
1. Induction Motor has an air-gap but transformer has no air gap rather it is mutually link. 2. Induction Motor has high no-load current than transformer. 3. Induction Motor is a dynamic device. 4. Induction Motor has high power factor.

What is matual induction?
Mutual (not 'matual') induction occurs when a changing current in one circuit induces a voltage into a second circuit. An example of mutual induction is a transformer.
Why induction motor current increase when load increase?
The slip is proportional to the load torque in an induction motor. This can also be seen as a reduction in speed causing extra current to be induced in the rotor to supply the increased torque.

What does a step up transformer do to increase the voltage of an electrical current?
A step-up transformer increases the voltage of an electrical current by having more turns in the secondary coil than in the primary coil. This causes the magnetic field to induce a higher voltage in the secondary coil, resulting in an increase in voltage.
A transformer can increase or deacrease what?
Voltage and current.
What is the cause of the current increase when an induction motor is loaded?
When load is increased , rotor speed decreases.Rotor speed decreases , the difference (Ns - Nr) increases (Ns being constant).(Ns - Nr) increases , slip increases .Slip increases , (r2/s) decreases.Rotor current = E2/((r2/s) + x2) increases ( since E2 is constant).Rotor current increases , corresponding input current also increases.
