To determine
Explain the meaning of calculated load.
Expert Solution & Answer

Explanation of Solution
Discussion:
The equivalent value of all the loads connected to a system is said to be calculated load. The power rating of loads differs for different applications. It is also defined as the estimated load for the nominal values.
According to article NEC 220, the calculations for branch circuit, feeder, and service load are made. When all the loads are considered with the proper multipliers, the calculated load is the final result that provides guidance to calculate various types of load. To calculate the loads, both the optimal and standard methods are provided.
Conclusion:
Thus, the meaning of calculated load is explained.

You are to design a 9-volt battery operated baseband PAM communication system that must last great than 10 years without replacing the batteries. The application requires a BER of <10^-4 and a data rate of 200bps. The channel can be modeled as AWGN with a noise power spectral density of 10^-9 W/Hz and a channel loss of 10 dB. (a) Estimate the required capacity of the batteries. (The battery life (hours) is equal to the battery volts times of the battery capacity (Amps* hours) divided by the total load (Watts)) and (b) Can you easily find this battery? If not, what would you suggest be done?arrow_forward3. You are on a design team tasked to design a system of remote sensors that use PAM. Here is what the team knows/assumptions: The remote sensor will use a single AA battery required to power the sensors. The system has a bandwidth of 2KHz and requires a data rate of 12 Kbps and a BER of less than 1*10^-4. The typical channel has maximum losses of 35 dB and a noise power spectral density is 10^-9 W/Hz. Your boss assigns you with the task of estimating how long the battery will last.arrow_forward
