When V = 208 volts and I = 15 amps, then three-phase power = 5,410W per five wires. (Recall that only the amount of current per amps determines the required thickness of the copper wire.)Knowing the maximum power of any branch is important for choosing the number and size of PDU(s...
The formula for calculating gain in current is: Gain in Current = Voltage / Resistance For example, if the voltage across a resistor is increased from 12 volts to 24 volts, and the resistance remains constant at 12 ohms, then the gain in current will be: Gain in Current = 24 volts / ...

The Basic Earning Power (BEP) formula is also referred to as a ratio. Basic Earning Power = Earnings before interest and taxes (EBIT) / Total assets Let's say the Acme Company's income statement shows a net income of $15,000, taxes of $3,000 and interest expense of $250. Therefore...
Power Factor Formula: The power factor is calculated as the cosine of the phase angle between the source voltage and current. What is Power Factor? In electrical engineering, the power factor (PF) of an AC electrical power system is defined as the ratio of working power (measured in kilowatt...
Question 1: In Column H is a simple formula to show the variance between columns G and F. How can I show a "null" in H when there is nothing in G? Question 2: Column F has a simple formula that ... Rex-Delson Answer 1: You can use IF funtion, if the Column G has no value...
Second Version of the (current) formula:I = V / R If a currentIflows through a resistor, and there is a voltageVacross theresistor.Rcan be calculated. Third Version of the (resistance) formula:R = V / I All of these variations of the so called "Ohm's Law" are mathematically equal...
