Question

Which equation results from applying Kirchhoff's Voltage Law to the pure inductor?

Options

• \[v-\frac{L}{i}=0\]

• \[v-L\frac{di}{dt}=0\]

• \[v+L\frac{di}{dt}=0\]

• \[v-Li=0\]

Answer 1

Kirchhoff's Voltage Law gives \[v-L\frac{di}{dt}=0\]. Thus, the applied voltage equals the inductor term \[L\frac{di}{dt}\].
