What happens to the current as the voltage is increased by the step up transformer?
Compare a transformer to a balancing act. Both side need to remain equal.
The primary side of the transformer is the supply side and the load is connected to the secondary side of the transformer.The load governs the current of the secondary side of the transformer and the voltage of the secondary side must match the voltage that the load required to operate.
The ratio of the transformer will determine what the voltage of the secondary side is as compared to the voltage that has to be applied to the primary.
The current of a step up transformer will be higher on the primary side that that of the secondary.
Apply voltage and current to this concept and you will see that the transformer will remain balanced.
The size of the transformer is always calculated from the secondary side of the transformer and the value is written in VA or KVA where V = voltage and A = amperage. Power factor is also taken into consideration when calculating the size of the transformer to be used.
What else can I help you with?
What happens when frequency is increased of transformer?
When the frequency of a transformer is increased, the core losses of the transformer increase due to increased eddy current losses and hysteresis losses. This results in a rise in temperature of the transformer. Additionally, higher frequency can affect the impedance of the transformer and alter the voltage regulation and efficiency.
What happens to voltage when current is increased?
current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.
What type of device is used to increased or decrease the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
Can a constant dc current can induce a steady state voltage in a transformer?
No, the current has to change for a voltage to be induced in the transformer.
What happens to the current in the circuit if the resistance is increased?
If resistance is increased, current decreases. Ohm's Law: current equals voltage divided by resistance.
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
What is the purpose of constant voltage transformer?
The term 'constant voltage transformer' is used to differentiate the operation of transformers that are intended to change voltage levels, from those intended to change current levels -a current transformer (CT), for example, is termed a 'constant current transformer'.
What is the incoming voltage from the current source to the transformer called?
the incoming voltage from the current source to the transformer is called primary voltage.....
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
What is the name of the device that changes the ratio of a current in voltage?
A transformer. it steps up / down voltage, and steps down / up current.
