AUTOINDUCTANCIA 1. Se pretende conectar un dispositivo electrónico cuya resistencia es de 175 a una fuente de fem por medio de un interruptor. El dispositivo ha sido proyectado para funcionar con una corriente de 36 mA, pero, para evitar que se dañe, la corriente no debe aumentar a más de 4,9 mA en los primeros 58 μs después de cerrar el interruptor. Con el fin de proteger el dispositivo, se conecta en serie con un inductor como muestra la figura. El interruptor en cuestión es S 1 . ¿Cuál debe ser la fem de la fuente? Suponga que la resistencia interna es insignificante. ¿Qué inductancia se requiere? ¿Cuál es la constante de tiempo? 2. En el circuito mostrado en la figura ε =120 V, R 1 = 30 , R 2 = 50 y L = 0,200 H. El

• The ability to access any universityâ€™s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLAâ€™s materials to help me move forward and get everything together on time.
