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.

What are the mechanical and electrical characteristics of a DC shunt motor?
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
Main difference between ac and dc motor?
Dc is an electrical term for direct current. Ac stands for alternating current. As you probably guessed a dc moter uses dc current and an ac moter uses ac current. P.S. Most home outlets use ac current.
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.
What is the current in the secondary coil fi the current in the primary coil is 5.0A 10 loops on primary coil and 20 on secondary coil?
If I am not wrong then you have asked about a transformer. And its a current transformer. By theory of voltage transformer we know that Vs/Vp = Ns/Np So for answering your question we need the value of number of turns in primary and secondary coil. But you can use this equation to find your answer if you have other values. By using ohmic law you can convert voltage to current.
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
Who is a rival of Edison?
Nikola Tesla Also George Westinghouse (famous for invention and commercialization of ac current as electrical system vs. Edison's dc current - Westinghouse won that one!)
What causes the direction of current flow?
I assume you are referring to oceanic currents (instead of electrical current). Oceanic current is divided into 2 types: Surface Ocean Current -- affected by wind. Deep Ocean Current --cause by water density (mineral rich vs clearer water) and temperature gradient (differences in heat)
What is the difference between electricity in a battery vs the electricity in an electrical outlet?
One is AC and the other is DC. AC- alternating current is used in electrical outlets DC- direct current is used in batteries. An electrical outlet in your house would have 120 volts (the ones you use most, your tv, lights, radio are plugged into) or 240 volts (the ones your stove and dryer plug into). A battery voltage varies widely: AA & AAA batteries have 1.5 volts, a 9 volt battery has 9 volts, your car battery has 12 volts.

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

Dc is an electrical term for direct current. Ac stands for alternating current. As you probably guessed a dc moter uses dc current and an ac moter uses ac current. P.S. Most home outlets use ac current.
What is the current value of a riyal vs dollar?
See link.
Current US vs Grivna rate?
11581.00 grivna =
Ac vs DC current?
DC (direct current) means the current flows only in one direction. In AC (alternating current), the current changes direction continuously (for example, 50 or 60 cycles per second).
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.
What alternator do?
This is an easy answer. The alternator is hooked (through wires blue and black) to the battery. So every time you start an engine the alternator kicks on and charges the battery. That's practically how it works. <><><> To add a bit to the above- an alternator produces an alternating electrical current (unlike a generator, which produces a direct current- DC vs AC) On modern cars, the alternator produces the current used to charge the battery, and operate electrical equipment on the car, such as lights, wipers, radio, etc.
