Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
What is a sentence with the word electric current in it?
The electric light bulb would not turn on because it was burnt out.
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
What name is given to the property of metals that allows electricity to pass through it?
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.
How can use of a fuse or a circuit breaker prevent a fire in a building?
The wiring in a building, is designed to take the current to devices, when working properly. If a device develops a short circuit, the current is massive and unlimited. Passing massive amounts of current through thin cables will make them heat up, just like the filament in a lamp. This will cause a fire. A fuse is simply a thin wire, that is designed to burn up, when too much current flows through it. It is a controlled burn, inside a specially designed container, at a specific location. As the fuse is in the supply line, when it breaks, the power is also broken and everything returns to a safe situation. A breaker uses a bi-metal strip or coil to monitor the current and tip a switch when too much current flows. Breakers however can be reset and not normally destroyed by a fault.
What do you call the complete path that an electric current flows through?
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.
What does an electric current act like when it flows through a wire according to Christian Oersted's hypothesis?
a magnet
What does an electric current act like when it flows through a wire. according to Hans christian oersted's hypothesis?
a magnet
How do magnets magnetic fields electric currents and metals connect?
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.
What is the continuous loop that an electric current flows through?
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.
A complete path for electricity to flow?
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.
What are the multiple connected pathways through which electric current flows?
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.
When does electric current behave like a magnet?
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.
What is a large stream of moving water that flows through the ocean?
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.
Electric currents and magnets are not related?
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.
Is electric current flows like water in a river bed a alliteration metaphor simile or hyperbole?
This is a simile because it compares the flow of electric current to the flow of water in a river bed using "like."
What effect does heat have on electric current flow?
Increasing heat can increase the resistance of the material through which the current flows, which can reduce the flow of electric current. However, in some cases, heat can also increase the kinetic energy of charge carriers, leading to increased current flow in certain materials like semiconductors.
