Пример: the plates of A FIXED capacitor CANNOT be moved to vary the capacity WHILE the plates of a variable capacitor CAN be moved to vary the capacity 1) THE SECONDARY WINDING of a transformer is connected to the LOAD RESISTANCE... 2) the PRIMARY winding RECEIVES energy... 3) A STEP-DOWN transformer DECREASES the primary voltage... 4) an AIR core transformer is used for HIGHT-frequency currents... 5) in STEP-UP transformer the number of turns of the secondary winding is greater than the number of turns of the PRIMARY winding...

Answer 1

1) THE SECONDARY WINDING of a transformer is connected to the LOAD RESISTANCE..WHILE 2) the PRIMARY winding RECEIVES energy.
3) A STEP-DOWN transformer DECREASES the primary voltage WHILE 4) an AIR core transformer is used for HIGHT-frequency currents.
5) In a STEP-UP transformer the number of turns of the secondary winding is greater, WHILE the number of turns of the PRIMARY winding is less.
