Essentially yes, this is the reason why many electronic cables are surrounded by a metal mesh. This mesh acts as a Faraday cage and helps prevents the wires inside it from acting as an antenna and picking up unwanted noise.
the body can act as a conductor
A material that allows electrons to flow freely is called a conductor. Conductors have low resistance to the flow of electric current due to the presence of free electrons that can move easily through the material. Common examples of conductors include metals like copper, aluminum, and silver. These materials are used in electrical wiring and circuitry to facilitate the movement of electrons.
it depends on the frequency of the current in question. the higher the frequency, the less depth in the cross-section the current flows. this is termed skin depth.
Internal resistance. The ideal current source has no internal resistance in parallel with it (if it was set to supply no current it would act as an open circuit), and all the current it supplied would have to flow through its load (even if the load was an open circuit, in which case the voltage across the current source would be infinite). A real current source has the practical limitation that it must have an internal resistance in parallel with it, therefor some of the current it supplied is bypassed through that internal resistance and never reaches the load (if the load was an open circuit, then all the current supplied is bypassed and the resulting voltage drop across the internal resistance limits the voltage across the current source).
A: When a transistor is saturated current can flow in both direction qualifying it as a switch
A clockwise direction
no it is good conductor because it has free electrons
metaliods trust me
You can explain the basic relationships:* An electrical current will be accompanied by a magnetic field. That is, it will act as a magnet. * If a conductor moves through a magnetic field (e.g., near a magnet), a current will flow through the conductor (if there is a closed circuit).
No. Electrodes are the positive and negative terminals in and open circuit. A conductor is a substance that an electric current will pass through. Electrodes are usually made of a conductor.
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
There is no such thing as an 'induced current'. What is 'induced' is a voltage. If the conductor into which that voltage is induced forms a complete circuit, then a current will result. But it's the voltage that's induced, NOT the current! The direction of the induced voltage is explained by Lenz's Law which, in simple terms, tells us that the direction of the inducted voltage is always such that it will oppose the change in current that causes it. So the induced voltage will oppose any increase in current, but will act in the same direction as a reduction in current.
A better simple approximation would be two antennas separated by twice the distance of the single antenna to the ground.
The force between two perpendicular current carrying wires is zero, as the magnetic field produced by each wire acts perpendicular to the other wire's current. As a result, there is no component of the magnetic force that can act along the direction of the wires.
why not.. it is possible specially in satellites where such kind of antenna's are known as transceivers that is they can transmit and receive at the same time.
The principle (not 'principal') of operation of a d.c. motor is that whenever a current-carrying conductor is placed within a magnetic field, a force acts on that conductor which is perpendicular to that field -in other words, the force acts to push the conductor out of the field. If a pivoted loop of wire is placed within the same magnetic field, the forces on opposite sides of that loop act in opposite directions to each other, and a torque is applied to that loop. If the relative directions of current and field are maintained, then the loop will continue to rotate -this is done through the use of a split-ring commutator, a type of rotary switch, which also acts to supply the rotating loop from a fixed external circuit.
Objects like metals, such as copper and aluminum, act as conductors by allowing the flow of electricity through them easily. Insulators, on the other hand, such as rubber and plastic, do not allow the flow of electricity and are used to prevent electrical current from passing through.
