We need to find the ratio of the Teeder peak to the total connected load.
The Teeder peak is 16 kW and the total connected load is 6 kW for each house, so the total connected load for the 4 houses is 4 x 6 = 24 kW.Now, we can calculate the diversity using the formula: Diversity = Teeder peak / Total connected load
Diversity = 16 kW / 24 kW
Simplifying this, we get:
Diversity = 2/3
So, the diversity is 2/3, which is equivalent to 16/30.
Therefore, the main answer is option (b) 16/30.
