Are Kirchhoff's rules applicable to both a.c. and d.c. ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Kirchhoff's Laws:**
- Kirchhoff's laws consist of two main rules: the Junction Law (or Current Law) and the Loop Law (or Voltage Law).
- The Junction Law states that the total current entering a junction must equal the total current leaving the junction, which is based on the principle of conservation of charge.
- The Loop Law states that the sum of the potential differences (voltage) around any closed loop in a circuit must equal zero, which is based on the principle of conservation of energy.
