The correct expression for the instantaneous current in a resistive ci

1.	The correct expression for the instantaneous current in a resistive circuit is?(a) i=Vm(sint)/R(b) i=Vm(cost)/R(c) i=V(sint)/R(d) i=V(cost)/RThis question was posed to me in an interview for internship.My query is from Alternating Current in a Resistive & Inductive Circuit topic in section Single Phase Series Circuits of Basic Electrical Engineering
Answer» CORRECT choice is (a) i=Vm(sint)/R The BEST I can explain: The instantaneous voltage can be written in TERMS of the maximum voltage in the following manner: v=Vm(sint) SINCE i=v/R, we can write,i=Vm(sint)/R.
