(b) State the limitations of Ohm's Law (3)

(c) 3 resisters of value 2 Ω, 4 Ω and 8 Ω are connected in series across a supply of 42 V. Find the current taken from supply and voltage drop across each resistor (10)

Reference Answer

### (a) Ohm's Law
Ohm's Law provides a fundamental relationship between voltage, current, and resistance in an electrical circuit. It states that:
> *The current flowing through a conductor is directly proportional to the potential difference (voltage) applied across its ends, provided that all physical conditions and temperature of the conductor remain constant.*
**Mathematical Representation:**
