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.
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
The electric light bulb would not turn on because it was burnt out.
AC current (alternating current) like in a wall outlet
I believe its a conductor, because an insallator is like a stirofoam cup for example, as it keeps the heat in the cup without burning your hands. An example of a conductor is a piece of metal because it is able to pass an electric current through the metal.
Current leads voltage (or voltage lags current) by 90° in a purely capacitive circuit. Try to remember it this way: capacitors resist change in voltage, hence the voltage lags (they resist voltage change because the voltage first goes to charging up the electric field in the capacitor).Inductors resist change in current (energy in an inductor is in the form of magnetic fields, which are caused by the current through the wire). Remember an inductor is a coil (like an electromagnet, or a transformer).
The complete path that an electric current flows through is called an electric circuit. It includes components like wires, switches, and resistors that allow the flow of electricity in a closed loop.
a magnet
a magnet
Magnets produce magnetic fields which can interact with electric currents to generate forces or induce currents in the conductive materials like metals. When an electric current flows through a metal conductor, a magnetic field is produced around it. This interaction forms the basis of electromagnetism and is used in various applications such as electric motors and generators.
The continuous loop that an electric current flows through is called a circuit. It typically consists of a power source (such as a battery), conductive wires, and components like resistors, switches, and light bulbs. When the circuit is complete, electrons can flow continuously through the loop, allowing electrical energy to be transferred and used.
Electric current is the flow of electric charge through a closed circuit. It is generated by a power source, such as a battery or generator, and flows through conductive materials, like wires, to power electrical devices. The flow of current is driven by the difference in electric potential, or voltage, between the positive and negative terminals of the power source.
currents can be thought of simply by flowing through a wire, though not always the case. It is convenient to think of current density which is the amount of current flowing through a cross sectional area, like water through the opening of a pipe, since electric current flows through many 3-dimensional objects.
Electric current flows through multiple connected pathways in a circuit, including conductive materials like wires, resistors, capacitors, and other components. These pathways form a complete loop for the current to flow from the power source (such as a battery) through the circuit and back again. The flow of current is driven by the potential difference, or voltage, between the two ends of the circuit.
Electric current behaves like a magnet when it flows through a wire, creating a magnetic field around the wire. This phenomenon is known as electromagnetism and is the basis for how electromagnets and electric motors work.
The stream of water which flows like a river through the ocean is a current. The Gulf Stream is the most significant such current which flows from the tropics to the northern latitudes.
Actually, electric currents and magnets are closely related through electromagnetism. When an electric current flows through a wire, it generates a magnetic field around the wire. Similarly, moving magnets can induce an electric current in a wire. This relationship forms the basis of electromagnetism and is utilized in various technologies like electric motors and generators.
This is a simile because it compares the flow of electric current to the flow of water in a river bed using "like."
