An electrical supply has a power output of $2.4\,\text{kW}$ when the potential difference (p.d.) is $240\,\text{V}$. The two wires linking the supply to a kettle each have a resistance of $0.50\,\Omega$, as illustrated. Calculate the power delivered to the kettle and the p.d. across the kettle.
- Apower $2.3\,\text{kW}$, p.d. $230\,\text{V}$
- Bpower $2.3\,\text{kW}$, p.d. $235\,\text{V}$
- Cpower $2.4\,\text{kW}$, p.d. $230\,\text{V}$
- Dpower $2.4\,\text{kW}$, p.d. $235\,\text{V}$
