LxW of building x 3 volt amps per sq. foot
LxW of building x 3 volt amps per sq. foot
This is an answer that must be determined from the course material. There are several ways to do this.
LxW of building x 3 volt amps per sq. foot
To calculate the total power consumption in watts, you can multiply the current in amperes by the voltage in volts. If the voltage is not known, you cannot directly convert amperes to watts.
calculate the total sum of lighting power and add 10% as safe operation of the transformer. then select a transformer for that rating. suppose your total lighting power is 300VA. add 10% of the total lighting power so the total power is 330VA. therefore your transformer size can be 330va or more. please follow IEE regulations.
Total Utility may be determined by summing up the marginal utilities of each unit consumed.
It was determined by total population.

Six, Voltage is the same in a parallel circuit but current divides to total the sum of each branch. See Kirchoffs current law.
If current is 3 amperes and resistance is 1.5 ohms, then voltage is 4.5 volts. (Ohm's law: voltage equals amperes times resistance) Power is volts times amperes, or 13.5 watts. A watt is a joule per second, so suppling 13.5 watts for 4.5 seconds produces 60.75 joules.
