A transformer is a device that converts electrical power to a different voltage and current potential. You may have one at your home that converts the 110-120 volt wall output to 6-12 volts. The input voltage is stepped down to a lower voltage; the input current is also stepped up by the same factor as the voltage is stepped down.

∙ 12y agoA current transformer is used to enable the measurement of heavy currents flowing through its primary winding, by using a low-current ammeter connected to its secondary winding. They are widely used in high-voltage systems because they also electrically isolate the ammeter from the high-voltage circuit for safety purposes.
They are also used to supply current inputs to high-voltage protection relays.

Why transformar primary refers to secondary?
All transformers contain both primary and secondary coils. The primary will refer to the secondary when the voltage is to high. As voltage increases, it passes down the power to the secondary for efficient distribution of power.
Current in which electrons flow in the same direction is called?
It's alternating current
Is the base current smaller or larger than the emitter current?
The base current of the emitter current is smaller.
Current from a battery is always?
Direct current, as opposed to alternating current.
Which is better for transmission alternating current and direct current?
Alternating current is better than direct current for transmission.
How do you say transform in spanish?
transformar(se) = to transform (oneself)
Why transformar is not called an amplifier?
because it does not amplify anything, it transformers voltage and current. "amplifier" implies that input powe is increased at the output by increasing the voltage or current, or both. With a transformer, power in equals power out minus losses. The power "gain" of a transformer is always less than 1, if you want to think of it in amplifier terms.
What does it mean by rm in electrical system?
RM-Conductor of Multiple stranded wires of circular cross section.
Why transformar primary refers to secondary?
All transformers contain both primary and secondary coils. The primary will refer to the secondary when the voltage is to high. As voltage increases, it passes down the power to the secondary for efficient distribution of power.
