Exam Question

(a) Differentiate between resistance, inductance and impedance in an a.c. circuit. (6)

(b) A circuit is made up from four resistors of value 2R, 4R, 5R and 1OR connected in parallel. If the current is 8.6A, find the voltage drop across the arrangement and the current in each resistor.

Reference Answer

### (a) Differentiation between Resistance, Inductance, and Impedance
This section differentiates the three fundamental properties that oppose current flow in electrical circuits. A tabular format is used for clarity.
| Feature | Resistance (R) | Inductance (L) | Impedance (Z) |
