Electric charges will flow through all sorts of substances, not just metals. It is also possible for charges to go through empty space, if the voltage is high enough - especially if an electrode is heated. Read about electron tubes.
On the other hand, with a phenomenon known as capacitance, a current can flow through empty space, even if no charges flow.

What is the term given to to the point where two opposite electrical currents meet?
node Any number of currents can meet at a node, not just two.
Is line to line voltage equal to line voltage?
Yes. By definition, a line-to-line voltage is indeed called a line voltage.For delta-connected, three-wire, systems comprise three line conductors. The line voltage is numerically equal to the phase voltage.For wye-connected, four-wire, systems comprise three line conductors and a neutral conductor. Any line-to-neutral voltage is called a phase voltage. The line voltage is 1.732 times the value of the phase voltage.
Kirchoff's law that states the sum of the currents entering the node is equal to the sum of the currents leaving the node on a parallel circuit?
KCL (Kirchoff's Current Law) applies to any circuit, not just parallel circuits. The sum of the currents entering a node will always equal the sum of the currents leaving the node. KVL states that the sum of the voltages around a closed loop is always zero.
Will a ground fault interrupter work at any outlet with only 2 wires?
Yes. GFCI receptacles do not rely on a ground conductor to work. They sense any difference between current flowing in the hot wire and current returning in the neutral wire. Under normal circumstances, these two currents will be exactly the same. If there is a difference, then some of the current is flowing from the hot to somewhere else, possibly through a person to ground. This causes the GFCI to trip. The National Electric code even permits an old 2-wire receptacle with no ground wire to be replaced with a GFCI 3-prong receptacle. No ground wire is used, and the GFCI must be labeled "No Equipment Ground". See NEC Article 406.3(D)(3)(b) and (c). This is the only legal way to install a 3-prong receptacle in place of a 2-prong without running a new ground wire.
Only some currents are able to produce magnetic fields?
No. Any current produces a magnetic field. Look at Maxwell's equations.
How do you make a radio antenna?
Any regular piece of wire will do.
What is the difference between electric currents and electric charge?
Electric current is a flow of electrons is a measure of the quantity of electrical charge passing any point of the wire in a unit time.And, electric current is measured in ampere (A).Whereas, electric charge is the quantity of electricity that flows in electric currents . And , it is measured in coulomb (C)
How could you produce a magnetic field using a wire?
Any time an electric current passes through a wire, this will produce a magnetic field. If you want to make the field stronger, loop the wire into coils. The more coils you make, the stronger the field will be.
How does series circuit travel?
The electricity follows the entire length of the wire. if any part of the circuit is broken, all the electricity stops moving in the circuit.
What properties make radio waves good for communicating?
The really nice thing about radio waves is that they will make the electrons in a piece of copper wire move; this means that they generate electric currents in the wire. In fact it works both ways: alternating currents in a copper wire generate electromagnetic waves, and electromagnetic waves generate alternating currents. The electric currents at "radio frequencies" (rf) are used by radio and television transmitters and receivers. I use frequencies of 145MHz (VHF), 14MHz (20m HF) and 3.7MHz (80m HF).
What are car stereo wiring color codes for a 1999 subaru impreza I live in new zealand will this make any diffirence?
The 1999 Subaru stereo wiring color codes are universal. The red wire is the positive wire. The black wire is the ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
What would make it not have any spark 1989 Honda Prelude?
Coil, distributor, bad wire.
Does a 1988 Honda 4trax 300 have a wire harness?
Yes but bonds does not make them any more
How is it best to couple wire cables to avoid damage?
It shouldn't make any difference. But if you have the time, why not.
What is difference similiarity currents and gyres?
similarity is currents form gyres. difference is currents are any movement of water in one specific direction and gyres are circular patterns of water
Does the sun travel around the sun?
That doesn't make any sense. If you ment, 1. "Does the sun travel around the earth?" or 2. "Does the earth travel around the sun?" The answer is 2.
Is it possible to make a watch that can make you time travel?
So far, time travel has not been achieved - not with a watch, not with any other device. It seems somewhat doubtful that it ever will be possible.
