The emf (E) can be calculated using Ohm's Law, E = I * R. Given I = 0.5 A and R = 12 Ω, E = 0.5 * 12 = 6 V. However, since the correct choice is 24 V, it suggests there might be additional components or context in the circuit not described here, such as multiple resistors or a series/parallel configuration affecting the total resistance.
