Can we convert ac circuit to dc if we consider the emf and current is rms?

Why you want to convert tho use theory for ac circuits

But is it wrong?

Sorta. In some cases you can use formulae for DC circuit (for example, average power), but not always (say instantaneous power)

Voltage and current must be in same phase for it right?

Yeah

But we do write Vrms = Irms x Z Z is impedance

Depends on the way you are interpreting and whats ur goal, lot of things we do to find answers are theoretically wrong
SirLancelotDuLac
The reason we do it is when we are asked "voltage reading" or ammeter reading, or power disspated in L-C,R-C circuit etc., because you are taking average of power, which is dependant on I^2 or V^2.
