- Technician A says when testing the voltage output, if the charging voltage is too high, the cause could be an open field wire from the regulator. Technician B says a loose or glazed drive belt could be the cause of too high charging voltage. Who is correct? A only B only Both A and B Neither A or B Technician A says that poor connection at the generator output wire can cause charging systems problems. Technician B says that many charging system circuits contain a circuit protection device. Who is correct? A only B only Both A and B Neither A or BI have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds. What's the procedure to connect the components? What's the Arduino code (C++) for this project?9.a. A servo system is oscillating at standstill. This is an indication thatA. the following error limit has been exceeded.B. a motor winding is open.C. the system gain is too high. 9.b. In a DC servo motor system, the tachometer feeds back a voltage that’s proportional to motor speed.Where does this voltage go to?A. The interpolator cardB. The driverC. The CPU in the main controller
