Consider the given circuit.
What will be the differential equation for Loop1?
1
V1(t) = L1\(\frac{di_{1}(t)}{dt}\) + M\(\frac{di_{2}(t)}{dt}\)
2
V1(t) = L1\(\frac{d i_{1}(t)}{dt}\) − M\(\frac{d i_{2}(t)}{dt}\)
3
V1(t) = M\(\frac{d i_{1}(t)}{dt}\) + L\(\frac{d i_{2}(t)}{dt}\)
4
V2(t) = L1\(\frac{d i_{1}(t)}{dt}\) + M\(\frac{d i_{2}(t)}{dt}\)
