What else can I help you with?
What will happen to frequency of current when voltage is changed using a step up or step down transformer?
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
How input frequency to the transformer influences its physical dimension when using a step down transformer is used using as as a step-up transformer?
In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
Which type of transformer is used in sonometer?
A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.
What happens to the transformer ratings when you use a three phase step down as a step up transformer?
Nothing. The same rating is applicable.
Are intermediate frequency transformers are step up transformers?
Intermediate frequency transformers can be either step-up, step-down, or 1:1. The term "intermediate frequency" relates to the frequency of operation, and not to the voltage or current conversion ratios. An "intermediate frequency transformer" is a special purpose transformer used for filtration purposes in radio reception, rather than voltage or current conversion, though a step-up or step down turns-ratio may be used in the design.
What is the use of step up and step down transformer?
step up transformer is to icrease the voltage but keeping the frequency same. step down is use to get less voltage than input given but of same frequency. Generally step down is use,we reqiure it in oor house(in mobile charger etc.).It is also use in rectifires.
What is the fuction of the step-up transformer?
Step-Up Transformers increase the primary voltage to a higher voltage, of same frequency.
What is the transformer and starter?
A transformer is a static device which is used to step up or step down voltage without changing frequency. A starter is a device used to start the motors.It is used to limit the starting current to a safe value.
When step down transformer is activated what happens?
Step down transformer reduces high voltage of main power line and distribute it to desired level of voltage usable by residence or devices.
What is the frequency of the secondary of a 230 volt step down transformer?
The frequency is dependant upon what electrical grid that you are connecting the transformerto. If you are connected to a 50 Hz grid, the transformer will output a voltage at 50 Hz. The same thing with the 60 Hz grid, the transformer will output a voltage at 60 Hz.
Which type of transformer is used in mobile charger?
The transformer used in mobile is pulse transformer which operates at very high frequency pulsating DC in order to make charger energy efficient and light weight.
