Vp(peak value)=?
Vrms=240
√2=1.414
Vp=240×1.414
=339.36≈339.4
PLS IF THERE'S ANY MISTAKE,I STAND TO BE CORRECTED.
Myschool pls can you throw more light on how u arrived at 339.5?
I've solved over and over again, it's still thesame thing,339.4.
Thank you very much.

there is correct options the question mean you should look for peak mean value which is Vr.m.s/√2, go and check new school physics Topic: simple A.C circuit
