Question on: JAMB Physics - 2017
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
A
240v
B
340v
C
480v
D
57600v
Ask EduPadi AI for a detailed answer
Correct Option: B
The relationship between the peak value and r.m.s value of electricity supply is given as
V(_{r.m.s}) = (\frac{V_o}{\sqrt{2}})
where Vo = peak voltage
∴ Vo = V(_{r.m.s}) × √2
= 240 × √2
= 339.5v
= 340v
