Definition: Electrical and mechanical systems possess fixed analogy and there exist similarity between the equilibrium equations of the two. This allows forming such electrical systems whose behavioural characteristics are similar to the given mechanical system . Such systems are known as analogous systems.
What are the analogous of resistance?
The mechanical analogy of electrical resistance is the loss of energy of a moving system through such processes as friction. A mechanical component analogous to a resistor is a shock absorber and the property analogous to resistance is damping .
What is analogy circuit?
Analogy: The water being pumped round a network of pipes is like electrical current flowing around a circuit . A pump increases the water pressure in the pipes and causes the water to move. ... The water flowing around the circuit is analogous to current in an electrical circuit.
How is the air circuit analogous to an electrical circuit?
3.2 Resistance to airflow
Frictional resistance to airflow in a drainage system is analogous to resistance in electrical circuits in that they both impede the flow of current (electrical or air) and both cause a drop in potential (voltage or pressure) in their respective networks.
What is analogous to current?
When describing voltage, current, and resistance, a common analogy is a water tank . In this analogy, charge is represented by the water amount, voltage is represented by the water pressure, and current is represented by the water flow. So for this analogy, remember: ... Pressure = Voltage.
What is an example of an analogy?
An analogy is saying something is like something else to make some sort of explanatory point. For example, “ Life is like a box of chocolates—you never know what you’re gonna get .” You can use metaphors and similes when creating an analogy. A simile is a type of metaphor.
How does a circuit work?
An electric current in a circuit transfers energy from the battery to the circuit components . ... In most circuits, the moving charged particles are negatively charged electrons that are always present in the wires and other components of the circuit. The battery pushes the electrons in a circuit.
The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit , provided the temperature remains constant.
What is the difference between resistance and impedance?
Resistance is a concept used for DC (direct currents) whereas impedance is the AC (alternating current) equivalent . Resistance is due to electrons in a conductor colliding with the ionic lattice of the conductor meaning that electrical energy is converted into heat.
What is an inductor analogous to?
for an inductor [Eq. (E. 3)], we see that the stored magnetic flux in an inductor is analogous to mass times velocity , or momentum. In other words, magnetic flux may be regarded as electric-charge momentum.
What is electrical pressure called?
VOLT – A unit of electrical pressure (or electromotive force) which causes current to flow in a circuit. One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance.
What components must be present to have a circuit?
- a conductive “path,” such as wire, or printed etches on a circuit board;
- a “source” of electrical power, such as a battery or household wall outlet, and,
- a “load” that needs electrical power to operate, such as a lamp.
How does current flow in a circuit?
The direction of an electric current is by convention the direction in which a positive charge would move . Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
What is difference voltage and current?
The important difference between voltage and current. Voltage is the potential difference between two points in an electric field , which causes current to flow in the circuit. Current is the rate of flow of electrons is called current. Voltage is the cause of current (being an effect).
What are analogous systems?
Definition: Electrical and mechanical systems possess fixed analogy and there exist similarity between the equilibrium equations of the two. This allows forming such electrical systems whose behavioural characteristics are similar to the given mechanical system . Such systems are known as analogous systems.
Voltage is the pressure from an electrical circuit’s power source that pushes charged electrons (current) through a conducting loop , enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).
