Current tranformers transform amps(current) and usually have ratios of 100/1 or 2400/1. They come in different classes and accuracy factors depending on the application which can be for instrumentation or protection.
Voltage Transformers transform voltage. Either up, like at power stations for transmission to distribution, or down, like your cellphone charger from your house supply to the low voltage your cellphone needs. Ratios are for example 6600/400 Volts or 110/12 Volts. they also come in different classes and ratings as needed.

What will happen current transformer connected in parallel?
If current transformers are connected in parallel, they will superpose and supply a high current. EDIT: I suppose you drive the transformer with a voltage source. By the way, it depends how you connect the transformers: A - primary side in parallel and two independent loads at the output B - primary sides in parallel and secondary sides in parallel Say turns ratio is Np:Ns, then for each transformer you have Vp/Np=Vs/Ns, Np*Ip=Ns*Is. IE If Np=N, Ns=1, you have a voltage step down transformer (Vs=Vp/n, Is=N*Ip) A: You will impose the same secondary voltage to each load, that is Vs=Vp/N. Input current is the sum of each output load multiplied by transformer turns ratio. If the two transformers have M and N turns ratio, you have Iin = M Is1 + N Is2 (Is1=Is2 only if loads are identical) This architecture is used in modular / redundant systems. B: Theoretically, it's like having a single transformer. In practice, I have never seen it. What you do is to split the current in two different cores, so that your losses will be lower for each core. That *could be handy if you wanna use ferrites which are undersized for your application and you don't want to buy a new one.
Why is the resistance vs current graph is not linear?
resitance is inversly proportional to current when (v) is kept constant <><><><><> Because resistance is a function of temperature.
Current electricity vs electrical current?
Current or "electrical current" (to distinguish it from current in a river) is the flow of electrons in a wire which can perform useful work. The current can be generated by a battery or a generator, or by other means. Current electricity is not a commonly used term. "Current electricity" is the science of electric currents, and it means the same thing as Electrodynamics. Example: the Electrical Sciences can be divided into two parts: Static Electricity or Electrostatics, and Current Electricity or Electrodynamics.
How designing stabilizing resistor in restricted earth fault relay?
To determine the value of Stabilizing resistor Rs = Vs/Is = If(Rct +2Rl)/Is Where, Rs = resistance value of the stabilizing resistor Vs = voltage at which the relay will operate Is = current flowing through the stabilizing resitor and the relay If = maximum secondary fault current magnitude Rct = internal resistance of the current transformer Rl = resistance of attached wire leads
How do you set out a line graph showing current vs voltage?
its like a bar graph but with little crosses and you join them up with lines

What actors and actresses appeared in Andy Biscuits vs. Transformers - 2009?
The cast of Andy Biscuits vs. Transformers - 2009 includes: Brent Triplett as Andy Biscuits
What does the slope of a graph potential difference vs current represent?
The slope of a graph of potential difference vs current represents the resistance of the component or circuit being analyzed. It is calculated using Ohm's Law: V = IR, where V is the potential difference, I is the current, and R is the resistance. A steeper slope indicates a higher resistance, while a shallower slope indicates a lower resistance.
What are the release dates for Andy Biscuits vs- Transformers - 2009?
Andy Biscuits vs- Transformers - 2009 was released on: USA: 12 November 2009 (Cucalorus Film Festival)
Distribution transformer vs power transformer?
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
What is skill gaps?
A skill gap is the difference between an employee's or potential employee's current skills vs. the skills necessary to meet or exceed expectations of the job.
Background information on skills gap?
A skill gap is the difference between an employee's or potential employee's current skills vs. the skills necessary to meet or exceed expectations of the job.
What is the relationship between voltage and current as shown in the graph of voltage vs current?
In the graph of voltage vs current, the relationship between voltage and current is linear. This means that as voltage increases, current also increases proportionally.
Transformers Vs Wall-e Which one is a better movie?
i con't know i would choose wall-e
What does the potential energy vs distance graph reveal about the relationship between potential energy and distance?
The potential energy vs distance graph shows that potential energy decreases as distance increases. This indicates an inverse relationship between potential energy and distance - as distance between objects increases, the potential energy between them decreases.
What does the current vs voltage graph reveal about the relationship between current and voltage in the given circuit?
The current vs voltage graph shows that there is a linear relationship between current and voltage in the given circuit. This means that as voltage increases, the current also increases proportionally.
