To calculate the voltage from power factor:
\[ V = \frac{W}{PF \times A} \]
Counting back days is a method used to determine a past date by subtracting a specific number of days from a given start date. This technique is commonly used in various fields such as project management, event planning, and historical research to calculate deadlines, milestones, or significant dates in the past. By knowing the start date and the number of days to count back, one can easily find the new date using simple arithmetic.
Let's assume the following values:
Step 1: Multiply the power factor by the current:
\[ PF \times A = 0.8 \times 10 = 8 \]
Step 2: Divide the power by the result:
\[ V = \frac{1000}{8} = 125 \text{ volts} \]
Let's assume the following values:
Step 1: Multiply the power factor by the current:
\[ PF \times A = 0.9 \times 15 = 13.5 \]
Step 2: Divide the power by the result:
\[ V = \frac{1500}{13.5} = 111.11 \text{ volts} \]
