WebKorecall Guide for On-hook and Off-hook phone line voltage. The Ideal phone line voltages should always be in this range only. Phone Recorder works ideally under this voltage... WebPower is P = V 2 / R so V = R ∗ P, so high impedance headphones will need a much higher output voltage because they require more power and have a higher impedance. Anyway, for the Sony MDR-EX51 headphones shown on the page linked above you can see that they are fairly close to a simple 17 Ohm resistor.

WebMar 12, 2024 · To get the phone to ring, an AC voltage of ~60V-105V is superimposed on the TIP/RING. Note that the RING in this case has nothing to do with a bell, but with a 1/4" phone plug, where the point is the TIP, and the remainder is the RING. This reference has several ring generator circuits and a good discussion of ringing. Share Cite Follow WebWhen a telephone is taken off the hook, the line voltage drops from 48 Volts to between 9 and 3 Volts, depending on the length of the loop. If another telephone in parallel is taken off the hook, the current consumption of the line will remain the same and the voltage across the terminals of both telephones will drop.
