The bulb is marked with the power (watts) and the voltage. Divide the watts by the volts and you have the amps.
I = p/v = 100w/9v = 11.11ai = p*v = 100w*9v = 900ai = (p/2)*v = 50w*9v = 450ai = p*2*v = 100w*(9v + 9v) = 8100a
To calculate the current required to melt 14 gauge wire insulation, you need to know the specific heat capacity and melting point of the insulation material. You then use the formula Q = mcΔT to calculate the heat energy required to melt the insulation, where Q is the heat energy, m is the mass of the insulation, c is the specific heat capacity, and ΔT is the temperature increase needed to reach the melting point. The current can be estimated using the formula I = Q / t, where I is the current, Q is the heat energy calculated earlier, and t is the time over which the heat is applied.
ilkovic equation gives us the chance to know what is the potential difference of any system.the potential difference can easily be calculated with the help of Hg-drop!there is an equation with the help of which we can know very other things except the potential difference!
To calculate the voltage, you need to know the current (amperage) as well. The formula to calculate power (watts) given voltage (volts) and current (amps) is: Power (P) = Voltage (V) x Current (I). Without knowing the current, it is not possible to directly convert watts to volts.
To calculate current passing through a light globe, you can use Ohm's Law: current (I) = voltage (V) / resistance (R). To calculate voltage across a light globe, you can rearrange Ohm's Law to solve for voltage: voltage (V) = current (I) * resistance (R). Just make sure you know the resistance of the light globe in ohms.
I = p/v = 100w/9v = 11.11ai = p*v = 100w*9v = 900ai = (p/2)*v = 50w*9v = 450ai = p*2*v = 100w*(9v + 9v) = 8100a
There are a great many equations for calculating current; it depends on the context in which you need to calculate current.
an equation that shows how to calculate the value of the next term in a sequence from the value of the current term
The equation to calculate electric power is P = IV, where P represents power in watts, I represents current in amperes, and V represents voltage in volts.

Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage
There are several formulas to find out leakage current, but one is the general electric current equation. This electric current equation is I=Qt.
Current Ratio = Current Assets / Current Liabilities
There is no such equation. The main reason is that there is no relationship between current and frequency.

current= area of surface x current density required / 1000 , weight of zinc anode = current x life of anode (4yrs) x 8766 / 780
The general equation for power in a BALANCED three-phase load is as follows:P = EL IL x power factor...where EL and IL are the line voltage and line current, respectively.So all you have to do is to manipulate the equation to make the line current the subject, and insert your figures.
