The correct expression for the instantaneous current if instantaneous voltage is Vm(sint) in a resistive circuit is?
A. 1A
B. 2A
C. 3A
D. 4A
This question was posed to me by my school principal while I was bunking the class.
Asked question is from Alternating Current in a Resistive & Inductive Circuit in division Single Phase Series Circuits of Basic Electrical Engineering
Right option is B. 2A
Easy explanation: We know that:V=Vm(sint)
Since i=V/R, we can write, i=Vm(sint)/R.
