A; Any components that provide gain/loss are active device resistors, capacitors are passive
Capacitors and inductors are considered passive elements, not active elements, because capacitors and inductors do not supply or amplify energy. An example of an active element is a battery, which supplies energy to a circuit.
Circuit parameters can be classified as:1-- Active or Passive2-- Linnear or Non-linnear3-- Unilateral or Bilateral4-- Lumped or Distributive1-- Active or Passive:Those circuit elements that supply energy to an energised circuit are called active circit elements. Eg.: Voltage source, current source,etc.Note: It is important to note that dependent sources cannot be placed under this category as they depend on the value of current or voltage in any other branch of the network.Passive circuit elements, on the other hand, are those elements that use up the energy supplied by the active sources and\or do not supply their own energy to the circuit.Eg.: Resistor, capacitor, inductor, etc.Note: It is important to note that a capacitor does store energy and also supplies it back to the circuit but this energy is not of its own, instead it's the energy supplied by some active component. Hence, it cannot be placed under the category of active circuit parameters.Thus an energised network(or a circuit) consists of both active and passive elements.2--
all passive elements which absorb energy from active elements can control the flow of electrons
A simple circuit consists of a source of electro motive force ( EMF or voltage V ) This could be a battery,dynamo or solar cell. The circuit should do something, like light a lamp. For the lamp to glow there must be a flow of electrons called an electric current measure in Amperes (I). For the current to flow the circuit must form a closed loop, like a daisy chain. A switch is a device that breaks this loop and controls the state of the circuit. Closed circuit, switch closed, = lamp on Open circuit, switch not closed = lamp off
The circuit is callaed lumped circuit whose elements can seprate(eg rectifier circuit in pcb). but in the distributed circuit we can seprate the elements from the circuit(eg transmision lines)
It is NOT active in the developing fetus.
Reciprocal circuit elements are those elements/circuits in which power loss/gain is same at both nodes/ends.In these types of circuits we can check the circuit or connect it in any way.
the group1 elements
a simple circuit is made with basic electronics elements
no
an opened circuit is considered to be possessed with an infinite resistance which totally opposes the flow of current in the circuit and ultimately makes the functioning of elements in the electric circuit subtle
An active power is the real component of the power of an alternating current circuit.
