This is an answer that must be determined from the course material. There are several ways to do this.
The total lighting load in amperes is determined by first calculating the total wattage of all lighting fixtures in a circuit. This total wattage is then divided by the voltage of the circuit (usually 120V or 240V) using the formula: Amperes = Watts / Volts. Additionally, factors like the power factor (for non-resistive loads) may be considered to ensure accurate calculations. It's also important to account for any local codes or regulations that might affect the overall load calculation.
In a parallel circuit, the total ampere draw is the sum of the individual currents. Therefore, if the readings are 2 amperes, 7 amperes, and 12 amperes, you add them together: 2 + 7 + 12 = 21 amperes. Thus, the total ampere draw of the circuit is 21 amperes.
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.
