What else can I help you with?
What are active elements in circuit?
A; Any components that provide gain/loss are active device resistors, capacitors are passive
What is the use of capacitors in fire alarm circuit?
Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.
What is the theory of astable multivibrartor?
An astable multivibrator is a type of electronic oscillator circuit that continuously switches between its two unstable states without requiring any external triggering. It consists of two active devices, typically transistors or operational amplifiers, and feedback components like resistors and capacitors. The circuit generates a square wave output, with the frequency determined by the values of the resistors and capacitors used. Astable multivibrators are commonly used in applications such as clock pulses, timers, and signal generators.
What is complete circuit?
A complete circuit is where a current can flow without any leaks.
Discrete products in semiconductors?
Resistors, capacitors, diodes any component that is a recognized item byitself as a single component.
Does adding resistors in series increase or decrease the overall resistance of a circuit?
Resistance in series adds together. two 100 ohm resistors in series are equivalent to one 200 ohm resistor. to make an equation out of it ( even though it is simple) you can say: Rtotal=R1+R2+R3...+Rn
Anything that slows down the flow of electric charge?
Any material that resists the flow of electric charge is considered a resistor. Resistors are used to control the amount of current flowing in a circuit, and they can be found in various electronic components. In simple terms, resistors slow down the flow of electric charge, helping regulate the flow of electricity in a circuit.
What is the difference between computer devices and computer?
A device is a generic term for any man-made object that has moving parts. A computer is an example of a device, but not all devices are computers.A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem.An electronic component is any physical entity in an electronic system used to affect the electrons or their associated fields in a desired manner consistent with the intended function of the electronic system. Components are generally intended to be connected together, usually by being soldered to a printed circuit board (PCB), to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Components may be packaged singly or in more complex groups as integrated circuits. Some common electronic components are capacitors, inductors, resistors, diodes, transistors, etc. Components are often categorized as active (e.g. transistors andthyristors) or passive (e.g. resistors and capacitors).
What is a complete path through which electricity can flow?
A closed loop of conductive material that allows electricity to flow from a power source to a device and back to the power source is called a complete circuit. It typically includes wires, switches, and components such as resistors, capacitors, and lightbulbs. If the circuit is open or broken at any point, electricity cannot flow.
In order to start the current flowing a circuit needs a?
In order to start the current flowing, a circuit needs a complete path for the electricity to travel, known as a closed circuit. Additionally, a power source, such as a battery or generator, is required to provide the necessary voltage. Components like resistors, capacitors, or switches may also be included to control the flow of current. If any part of the circuit is open or broken, the flow of current will be interrupted.
What blocks current flow?
Resistors "resist" current flow. The ultimate "blocking" resistor is an open circuit, having a resistance of infinity (for all practical purposes) ohms.Capacitors also resist a change in voltage drop. For the case of a DC circuit, a capacitor, after reaching equilibrium, will present a DC resistance of infinity. For the case of the AC circuit, a capacitor will allow the AC signal to pass, while blocking any DC bias that might be present.So, resistors and, in the DC case, capacitors, block current flow.
What do the straight lines represent in a circuit?
In a circuit diagram, straight lines typically represent conductive pathways, such as wires or traces, through which electrical current flows. These lines connect various components, such as resistors, capacitors, and power sources, allowing for the transfer of electrical energy. The straightness of the lines indicates a direct connection without any junctions or branches.
