Question

A generator's maximum output is 220 V. What is the rms potential difference?

Answer 1

The rms potential difference of the generator with a maximum output of 220 V is approximately 155.56 V.

Step-by-step explanation:

The root mean square (rms) potential difference of a generator with a maximum output of 220 V can be calculated by dividing the maximum value by the square root of 2.

Therefore, the rms potential difference is 220 V divided by √2, which is approximately 155.56 V.

Answer 2

The rms potential difference is defined as the peak value of the potential difference divided by the square root of 2:

`V_(rms) = (V_0)/( √(2) )`
where

`V_0` is the peak value of the voltage (the maximum voltage).

The generator in our problem has a maximum voltage of
`V_0=220 V`, so its rms potential difference is

`V_(rms)= (V_0)/( √(2) )=155.6 V`
