The formula for the electric current can be given as I= Qt where Q refers to coulomb charge and t= amount of time in second . By applying this formula the amount of current passing through the conductor can be known foor any instant of time. For any conductor the amount of charge is always constant.
Current measures the flow of moving charge per unit time. Therefore the formula for current is I=Q/t as the unit of current is C/s (Coulomb's per sec) or amps (A).

∙ 9y agoOhm's law shows that current is directly proportional to the difference in potential across two points. This means that current (I) is equal to potential difference in volts (V) divided by the resistance of the conductor in ohms (R), or I = V/R, and measured in amperes.

∙ 13y agoThe Starting current is equivalent to Locked Rotor Amperes (LRA), it may be displayed on the the manufracturer's specification plate. Generally, LRA = Full Load Amperes x 6-7 times.
For Example, If FLA of a Motor is 55 Amps., then LRA = 55 x 7 = 385 Amps. i.e. for less than a second only.

∙ 14y agoThat depends, on the basis of what you want to calculate it. Quite often, Ohm's law is used: voltage = current x resistance.

∙ 9y agoCurrent in amps is equal to the voltage divided by the resistance in ohms.

How do you calculate voltage drop for starting motor current and how to get the starting pf?
How do you calculate voltage drop for starting motor current
Can you calculate power by multiplying voltage and current?
Not enough information. Power = current x voltage. Since voltage can be anything, there is no way to calculate power. Time is irrelevant; though once you have the power, it can help you calculate energy (energy = power x time).
How can calculate the current of 3 resistors wired in parallel?
In this case, to get the equivalent resistance, first you use the parallel formula (1/R = 1/R1 + 1/R2) to calculate the equivalent resistors in parallel. Then you calculate the series resistance of this combination, with the other resistor.

How do you calculate starting current of 380 volts 3phase 50 hertz AC motor?
Dear Sir,I want to know that how much draw starting current of 380 volts 3 phase 50 hertz AC motors as per rating values?
How do you calculate dg current?
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
What is starting current?
A starting current is the first current and power produced by a machines engine or electrical device. The starting current is used to determine the engines natural strength.
What would be the starting current of any Air Conditioning if voltage is 220?
To calculate the starting current of a motor, the run current must be stated. The voltage is only associated with this calculation in as the higher the motor's voltage is the lower the run current is. The start current can be as high as 300 to 600 percent of the run current. Also taken into account, without the specific make and model of the A/C, the run current is hard to guess as there is quite a variety of amperage drawn by these units.
How do you calculate DG set current?
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
