Another perspective is the use of the electronic component known as transformer by any electronic device like an AVR
The function of a transformer in any electronic device is to step down the 220VAC to a lower AC voltage (typically 12VAC) before its converted to DC voltage required by the rest of the electronic components of the AVR. Its made up of 2 coils, the primary & the secondary. The primary is connected to the 220 outlet & the secondary is attached to the AC to DC conversion circuit of the AVR
If the power switch is not located between the 220 plug and the primary coil of the AVR will continuously consume electricity if its kept plugged because there is a complete circuit between the 220 outlet and the primary coil of the AVR transformer

August 7th, 2015 08:18 AM #2does this mean that if the switch is located between the 220 plug and the primary coil the avr is not consuming electricity even if its plugged in the 220 socket?

August 7th, 2015 08:22 AM #3That is correct bro,- no electricity consumption as you cut it off from the main. Originally Posted by box_type

Vampire consumption (current term) is mainly due to the transformer (hysteresis)....
