the A represents the surface area, and the Greek letter theta (θ) represents the angle between the normal vector and the field lines. The subscripted E next to phi indicates that the formula is specific to electric flux.
To solve the problem, we need to calculate the electric flux through a square area when an electric field is present. The formula for electric flux (Φ) is given by:
According to Gauss's law, the electric flux (Φ) through a closed surface is given by the formula:Φ=Qε0where:- Φ is the electric flux,- Q is the charge enclosed (in coulombs),- ε₀ is the permittivity of free space, approximately 8.85×10−12C2/N m2. Step 3: Substitute ...
It is because the total flux linking each coil is less than its own flux.Mutual Inductance FormulaWe know that any change of current in one coil is always accomplished by the production of mutually induced e.m.f. in the second coil....
We can combine this formula with the formula for wattage to incorporate resistance into our calculations. The first step is to revise the wattage formula by dividing both sides of the equation by V: W = VA A = W/V The updated formula indicates that one amp equals one watt divided by one...
In mechanics, the length, mass, time, temperature, and electric current are taken as three base dimensions, and meter, kilogram, second, ampere, kelvin, mole, and candela are the fundamental units. The dimensional formula of individual quantities is used to establish a relationship between them ...
But if you need a specific voltage drop, you can use the voltage drop formula below: Reducing DC Voltage with Resistors From the above formula, you can get the voltage across the resistor R2. That is the voltage you need. But from this formula alone, you cannot find the resistance of ...
