When the r.m.s value of a source of electricity supply is given as 240v, it means that the peak value of the supply is
- 240v
-
340v
- 480v
- 57600v
The correct answer is: B
Explanation
The relationship between the peak value and r.m.s value of electricity supply is given asV\(_{r.m.s}\) = \(\frac{V_o}{\sqrt{2}}\)
where Vo = peak voltage
∴ Vo = V\(_{r.m.s}\) × √2
= 240 × √2
= 339.5v
= 340v
