Which circuit element(s) will oppose the change in circuit current ?
Correct answer: B. Inductance only
- A. Resistance only
- B. Inductance only
- C. Capacitance only
- D. Inductance and capacitance
Explanation
Inductance opposes a change in current by producing a back emf, e = -L(di/dt). Resistance opposes current itself, while capacitance primarily opposes a change in voltage.
