There is a magnetic-potential drop across an air gap. If you represent a magnetic core with a winding current i as a magnetic circuit. The magneto-motive force will be your voltage source, where the mmf (magneto-motive force) = Ni; (number of turns on the core and current product) == ∫Hdl=mmf=N*i. The elements that would be in the circuit would be in series and it would be represented as two "resistors" or better known in magnetics as the reluctance of the material which has a parallel equivalence to the resistor's characteristics.
Reluctance=Rmk=length of material divided by the product of the Area and permeability of the material µ.
Rmk=lk / (µk*Ak); where k is the number of of "legs" of the core or different mediums you approach.
To answer the air gap problem, the air gap would have a Reluctance where µ = µ0, permeability of free space and the Area of the Magnetic flux would be the same size of the area of the core. Finally the length would be the size of the airgap=δ.
Now since you have the reluctance of the airgap rmδ= δ /(µ0*Area of core). The Magnetic Drop is now = Umk where k is δ = Umδ = mmf / Rmδ = µ0*Area*N*i/δ
What else can I help you with?
A parallel plate capacitor has a plate separation of 1.0 mm How much potential difference can be placed across the capacitor before dielectric breakdown of air occurs?
You need more information than this to find your solution. There will be a a value for the electric field at which point the air will break down. you also need the area of one of the capacitors and the capacitence
Why a ring main is used in a compressed air distribution system?
Ring main distribution system allow compresssed air to converge from two directions. So this reduces pressure drop and mades changes to the system easier.
What electrical device is a diaphragm found in?
A diaphragm will be found in both a microphone, and a speaker; both being transducers across electrical to air pressure.
What is a ducter tester?
A duct tester is a specialized device used to measure the airtightness of ductwork in heating, ventilation, and air conditioning (HVAC) systems. It helps identify leaks and inefficiencies in duct systems by pressurizing or depressurizing the ducts and measuring the airflow and pressure drop. This information is crucial for ensuring optimal system performance, energy efficiency, and indoor air quality. Duct testers are commonly used during building inspections and energy audits.
Why leakage conductance is neglected in overhead lines?
The shunt conductance is due to leakage currents flowing across insulators and air. As leakage current is considerably small compared to nominal current, it is usually neglected, and therefore, shunt conductance is normally not considered for the transmission line modeling.
What are the air sacs in a mammalian lung across which gas exchange occurs?
Alveoli
What is Temperature drop across air conditioning coil?
The temperature drop across the coil is dependent on the relative humidity of the air, the wet bulb reading of the R/A, and the ambient temperature of the home. But a good rule of thumb is in between 17 and 22 degrees Fahrenheit.
What term is defined as erosion that occurs in open air?
The term defined as erosion that occurs in open air is "aeolian erosion." It refers to the process of wind eroding and transporting rock particles or sediment across the Earth's surface.
Why does precipitation occurs?
Precipitation in the water cycle occurs when water vapor condenses from the air and falls as water or ice. Normally this is caused by cooling either from an air mass or from a temperature drop at higher altitude. Precipitation in a chemical reaction occurs when chemical products are insoluble in a solution, or when the solution cannot hold the total volume of solutes present.
What should average temp drop be across home ac coil?
The average temperature drop across a home air conditioning coil, known as the temperature split, should typically range between 15 to 20 degrees Fahrenheit (8 to 11 degrees Celsius). This drop indicates how effectively the system is cooling the air. If the temperature drop is significantly lower than this range, it may suggest issues such as low refrigerant levels or airflow problems. Conversely, a higher drop could indicate a restriction in airflow or other system inefficiencies.
What do you mean by condenser airside pressure drop?
Condenser airside pressure drop refers to the decrease in pressure that occurs as air passes through the condenser coils in an air conditioning or refrigeration system. This pressure drop is influenced by factors such as the design and cleanliness of the coils, air velocity, and any obstructions that restrict airflow. A higher pressure drop can indicate reduced efficiency and performance issues in the system.
What type of fog occurs as warm moist air moves across a cold surface?
The type of fog that occurs when warm, moist air moves across a cold surface is called "advection fog." This phenomenon happens when the warm air cools and condenses as it comes into contact with the colder surface, typically water bodies or land. Advection fog is often seen near coastlines and can reduce visibility significantly.
Is a sudden drop in air temperature stimulus or response?
The sudden drop in air temperature is a stimulus.
Is the sudden drop in air temperature a stimulus or response?
The sudden drop in air temperature is a stimulus.

How come water from AC?
Because the amount of water vapour that the air can carry before condensation occurs varies with temperature. If you take hot humid air aind cool it down some of that humidity will drop out as condensation - turn into water.
