Simple - we just look at the meaning of electrical current.
Electrical current is the movement of billions of tiny electrons moving along a conductor, like a wire, for instance. In order to move, these electron have to be 'pushed' by a force that we call EMF or just Volts. The electrons are also 'pulled' from the other side by Volts, as well. Electrical current will not move unless it is both pulled and pushed, which requires a complete, unbroken loop of some kind of conductor. If you break that loop, called a 'circuit', then no current can flow.

What material does not conduct heat or electrical current?
hmmm i also have the same question but i cant find it.
Why TEM wave cannot propagate thorough a rectangular waveguide?
TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. In hollow waveguides (single conductor), TEM waves are not possible, since Maxwell's Equations will give that the electric field must then have zero divergence and zero curl and be equal to zero at boundaries, resulting in a zero field.

What is the fundamental quantities in units?
The 7 Fundamental Quantities are: length, time, mass, electric current, temperature, substance and amount of light. SI units: metre, second, kilogram, ampere, kelvin, mole, candel. Symbols of units: m, s, kg, A, K, mol, cd. Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
Why He-Ne laser is continuous?
he ne laser has emmisions due to atleast three diffrent levels leading to three diffrent wavelenght of photons emitted..also as opposed to ruby laser which uses xenon flash tube , which gets highly heated and cant be used continously to exite the elctrons , a he-ne laser uses a high potential source like a tesla coil wich can be used continuously..

What is the name for the status of a circuit that has breaks which electric current that cant flow?
The name for the status of a circuit that has breaks which electric current that can't flow is called a Closed Circuit. Electric current cannot flow through an open circuit.

Why would a toy car need less solar energy than a real car?
because it is smaller and cant hold as much electric current
Carnivores can exist in a plant free world if their prey would reproduce enough?
no because their prey will not have anything to eat so it will start to die and if they cant eat they cant live, if they cant live then they cant reproduce, if they cant reproduce then the carnivores will die. So to speak, if one thing in the food chain is gone most likely the whole chain is broken.
Can electric plugs be lubricated?
No it cant
Can humans exist in space?
Humans can exist in space for short periods of time, but they require special equipment like spacesuits and spacecraft that provide oxygen, temperature regulation, and protection from radiation. Extended stays in space can have negative effects on the human body, such as muscle atrophy and bone density loss, so it is important to take precautions and conduct thorough research on the effects of long-term space habitation.

Where do you by an electric skateboard?
You cant buy an electric skateboard, but you can buy an electric scooter. If you want an electric skateboard your going to have to make it yourself. Good luck!
