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.
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.
resitance is inversly proportional to current when (v) is kept constant <><><><><> Because resistance is a function of temperature.
mechanical characteristics can be drawn between speed and torque electrical characteristics are 1. Output power vs speed 2. Output power vs input power 3. Output power vs efficiency 4. Output power vs torque 5. Output power vs line 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.
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

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.
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.

According to Ohm's Law, R = V/I, the physical meaning of slope for voltages vs current graphs is resistance.
