EL resultado de la intensidad total de un circuito eléctrico en serie cuyas resistencias son 12, 15,10 respectivamente tiene las siguientes respuestas, sabiendo que su voltaje es 25Voltios ¿Cuál es la correcta?

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
