2. Suppose the inner and outer solenoids are used as the primary and secondary coils respectively, the inner solenoid is connected to the Output Ports of the signal generator on 850 interface as shown in Fig. 2. If the signal amplitude from the signal generator on 850 interface is set to 10 V, the 850 interface will be crashed. Explain the cause of the crash (hint: resistances of the inner and outer coils are 0.4 and 77 0 respectively). 3. Can a transformer convert dc voltage? Why? 775. An electric doorbell requires a 12 V, 60 Hz ac supply. (a) What turn ratio is required on a transformer to operate from a 120 V, 60 Hz ac supply? (b) Is this a step - up or step - down transformer? of belennog al blogelon doorbell? (c) If the transformer is connected the wrong way around the circuit, what voltage is supplied to t
