Current Transformers are not voltage transformers. Current transformer are used for metering or protection purposes, with single turn primary. Generally the secondary current is either 1Amps or 5Amps.

Condensation occurs in the atmosphere as part of the phases in rain cycle. During the condensation phase, water vapor transforms into liquid form. When warm air rises into the atmosphere, it cools down and loses its ability to hold water vapor resulting to the condensation of water forming cloud droplets.
No, 10 dB is perceived to be twice as loud, and requires 10 times the power.Doubling of the volume (loudness) should be perceived by a level difference of 10 dB − psychoacousticians say.Doubling the sound pressure (voltage) level corresponds to a measured level change of 6 dB.Doubling of acoustic power (sound intensity) level corresponds to a calculated level change of 3 dB.Scroll down to related links and look at "How many decibels (dB) is twice (double, half) or three times as loud?"

A transformer has a primary and a secondary side. There is a ratio of windings from one side to the other that dictates whether it is a step up or step down transformer. The transformer is usually marked as to the input and output specifications. The current is directly proportional to voltage. If you had a transformer that was a step up from primary to secondary, it would be step down from secondary to primary.
A transformer. it steps up / down voltage, and steps down / up 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.
No. A step-down transformer's secondary voltage is lower than its primary voltage. The secondary current is determined by the load, and this causes a higher current in the primary winding.
A transformer. it steps up / down voltage, and steps down / up current.
A current transformer step downs the current in a power circuit to a lower amperage. A voltage transformer steps down the voltage in a power circuit, typically to 110 volts AC for residential and business use.
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
In transmission lines there is a massive current, we use CT to make this current measurable i.e. it steps down the current but DT is used to step down the voltage
Actually current transfomer is step up voltage transformer n step down current transformer as current transfomer is having single primary turn of thick conductor but having more number of secondary turn of thin wires..so wkt tansformer ratio k= n2/n1=v2/v1=i1/i2. so it steps up volatge n steps down current...so we use current transformer as a step up transformer almost in all generating stations. Current transformers typically have terminals for a voltmeter on their case and a hole through that case. If you run your current carrying lead through the hole and connect an appropriate voltmeter (the voltmeter's design and resistance may affect the results) to the voltage terminals, the voltmeter will indicate the current in the lead times some factor which should be marked on the current transformer. If you thread the current lead through the hole N times then the voltmeter will indicate N times what it would read with the lead going through once (assuming that the ampere turns resulting do not cause saturation of the transformer's core.
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
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.
The purpose of a transformer is to transform one voltage to another voltage. This can be in the configuration of stepping up the voltage or stepping down the voltage . The load is what establishes what the current from the transformer is going to be.
