Draw a power supply based on a 2x9V efficient mid-point transformer and a full-wave rectifier plus filtering. If the diodes each have a waste voltage of 0.7V, what will be the maximum voltage of the capacitor? What is the purpose of a zener diode? Give its electrical symbol. We use two cables of length 1 = 2 m and of section s = 10 mm² to start a vehicle whose battery is discharged, linked to a battery of 12 V of a second vehicle. Calculate the available voltage for a starter of a petrol vehicle requiring 100 A and a diesel vehicle requiring 250 A. Which conclusion can you give? We give the conductivity of the copper wire y = 6.107S.m-1.
