ohm law can apply in both ac & dc

in dc : V=IR

in ac : V=IZ (where assume z = r)

Answer / deepak

ohm law apply both ac& dc in case ac. v=ir

Answer / e.subhash

cant use every place some limitation is there.

Ohms law is most applicable for only DC system.

As per Ohms Law I = V/R , V=IR AND R=V/I

In DC power system only resistance come to circuit

In AC system resistance,capacitance and inductance come to circuit.

so here Instead of R considered Z (impedance) Z= R+XL+XC.

We use ACB in LT and VCB in HT.But if we use VCB in LT and ACB in HT that what will be the effect on the system or any power range?
