What do you mean by passive and active elements in a electrical network?
Passive elements don't require power from the supply to produce its effect on a signal. They derive the power of the input signal to perform its action. for example, a resistor doesn't require a separate supply to provide its action of resistance in a circuit. Where as in active elements there should be a power source for its working. They require a supply for there working. For instance, transistors - Only after biasing the transitor in required region of operation, its characteristics are applied on the signal. ie, for amplification, transistor require a source from where it can work in.
Does passive transport require sugar?
no, that's why its called "passive".
What is the type of circuit called when it has an conductor a switch a electric cell a resistor?
it is called a circuit and when it is closed is called a closed circuit and when open circuit it is called an open circuit
Is osmosis a type of transport involving elements such as calcium?
Osmosis is a type of passive transport that involves elements such as calcium. The elements are moved from high concentration to low concentration.
What is the movement of sucrose molecules called?
Passive
Why there is phase shift in AC circuit?
due to presence of passive elements
What stops the flow of electrons in a circuit?
all passive elements which absorb energy from active elements can control the flow of electrons
What are elements of a circuit?
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
What are active elements in circuit?
A; Any components that provide gain/loss are active device resistors, capacitors are passive
Are capacitors and inductors active elements?
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.
Is resistance is a passive element?
Resistance is not considered a passive element in the context of electrical circuits. Passive elements are components that do not introduce energy into the circuit, such as resistors, capacitors, and inductors. Resistors, however, dissipate energy in the form of heat and actively oppose the flow of electrical current.

The elements which are not capable of delivering energy by its own are known as?
passive elements
Is osmosis a type of passive transport involving elements such as calcium?
Osmosis is a type of passive transport that involves elements such as calcium. The elements are moved from high concentration to low concentration.
What is a passive element in a circuit?
A passive element is an element of the electrical circuit that does not create power, like a capacitor, an inductance, a resistor or a memristor.
What is a circuit parameter?
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--
What are the distributed and lumped circuit?
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)
