because their effects are desired to make the circuit work
A; Any components that provide gain/loss are active device resistors, capacitors are passive
Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.
A complete circuit is where a current can flow without any leaks.
Resistors, capacitors, diodes any component that is a recognized item byitself as a single component.
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
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.
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).
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.
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.
In the case of many electronics, you can discharge any capacitors by first unplugging it (and disconnecting any batteries) and then pressing the power button. The capacitors should drain when the circuit is opened.
Most circuit designers usually choose capacitors over inductors to perform similar tasks
A transformer is the primary device which transforms voltage to a higher or lower voltage. In electronics, capacitors and resistors perform this function.
