Answer:
The formula to find the voltage is:
And the voltage is 4 volts
Step-by-step explanation:
To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?
First, multiply both sides with R:
That would result into removing the divisor R from the right side of the equation:
Next, square-root both sides:
That would result in removing the square of v from the right side of the equation:
Thus we get the equation, .
To find out the voltage, simply replace R with 32 and P with 0.5
Thus, the voltage is 4 volts.
