Two resistors, 8 Ω and 12 Ω, are connected in parallel across a 24 V battery.
(i) Calculate the equivalent resistance of the parallel combination and the total current drawn from the battery.
(ii) Determine the power dissipated in each resistor individually.
(iii) Find the total power supplied by the battery using the equivalent resistance.
(iv) Show that the sum of the individual powers obtained in part (ii) equals the total power calculated in part (iii). Explain briefly why this agreement is expected.
