Best Answer

The formula is: current (in amps) = power (in watts) , divided by (240 times the power factor).

The power factor is 1 for incandescent light or heaters, otherwise it can be assumed to be 0.75 for other loads.

What is the formula for Kirchoff's current for parallel circuits?

Kirchoffs's current law states that the sum of all the currents flowing out of any point is equal to zero. In other words, the current flowing in is equal to the current flowing out.In the case of a parallel circuit, this means that if a single current branches into two or more parallel branches, then the sum of the currents in the parallel branches must be equal to the original current before it branched.


How should I calculate this. A single phase transformer is rated at 99kVA The primary voltage is 6.6kV and the secondary voltage is 220V Assume no losses and calculate The full load primary current?

First find the ratio of the transformer. 6600/220 volts. Second find the secondary current, I = W/E, 99000/220. Third divide the secondary current by the transformer ratio. The answer will be the primary current. To check your answer (W (or VA) = V x A) multiply the primary current times the primary voltage and the secondary current times the secondary voltage and they should both equal the transformer's kVA.


How do you calculate cable size for 50 hp?

just apply the formula :-p=v*i*cos(angle);now you have the power rating,load so in turn power factor so you can easily calculate the value of current.with the help of current you can chose the cable available in the market either the aluminum or copper wiresatendra.svnit@gmail.com


How do you calculate the size of cable for 1000kw generator?

To calculate the size of cable for a 1000kW generator, you need to consider the generator's voltage and the distance the cable will run. You will need to calculate the current the generator will draw at full load using the formula: Current (A) = Power (W) / (Voltage (V) x Power Factor). Once you have the current value, you can use it to determine the appropriate cable size based on the current carrying capacity of different cable types, factoring in voltage drop considerations for the distance the cable will run.

What is the impedance of a single phase inductive circuit having a voltage of 240volts and a current flow of 10amps?

Work it out for yourself. The equation is: Z = E/I, where Z is the impedance, E is the supply voltage, and I is the load current.


How do you calculate the current for single phase water heater?

To calculate the current for a single-phase water heater, you can use the formula: Current (A) = Power (W) / Voltage (V). Determine the power rating of the water heater in watts and the voltage it operates at (usually 120V or 240V in residential settings), then divide the power by the voltage to find the current in amperes (A).


Is it true that a formula can consist of a single cell reference?

It is possible for a formula not to have any cell references. Lots of functions do not use any values. To show the current date you could have the following in a formula:=TODAY()You could have a formula with a single cell reference with some operation being done on it:=B4*10You can have a formula that just has a cell reference which will just request that the current cell displays what is seen in another cell:=B4It is possible for a formula not to have any cell references.

What does formula mean in mathematical terms?

A mathematical formula is a statement which, given all but one of a set of variables, allows you to calculate the possible value(s) of the missing variable. Many formulae will give single solutions but the quadratic formula, for example, usually has two solutions.


How calculate electrons?

To calculate the number of electrons, you need to know the total charge of the system or material in question and the charge of a single electron (approx. -1.6 x 10^-19 coulombs). By dividing the total charge by the charge of a single electron, you can determine the number of electrons. Formula: Total number of electrons = Total charge / Charge of a single electron.

What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?

To calculate the amperage draw, you can use the formula P = V x I, where P is the power in watts, V is the voltage in volts, and I is the current in amps. Given that the power is 1200 watts and voltage is 120 volts, you can rearrange the formula to solve for current. Therefore, I = P / V, so the amperage draw of the heater would be 10 amps.


What are brackets used for when creating a formula or calculation?

Brackets are used for creating an array formula.From Microsoft:An array formula is a formula that can perform multiple calculations on one or more of the items in an array. Array formulas can return either multiple results or a single result. For example, you can place an array formula in a range of cells and calculate a column or row of subtotals. You can also place a formula in a single cell and calculate a single amount. An array formula that resides in multiple cells is called (logically enough) a multi-cell formula, and an array formula that resides in a single cell is called a single-cell formula.To multiply the values in the array (the cell range C2 through D11), select cells E2 through E11, and then enter the following formula in the formula bar:=C2:C11*D2:D11Press CTRL+SHIFT+ENTER to enter the array formula (and observe the brackets in the formula).TIP: If you later go back and edit the array formula, remember to press CTRL+SHIFT+ENTER. Don't just press ENTER or you will destroy the array formula and display an error message until you go to the cell and press CTRL+SHIFT+ENTER again.
