In the USA, should be 500 or 600 Ohms. It is 600 ohms as standard
coaxial cable
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.
480 volts and 60ohm impedence current = volt/impedence current=480/60 current=8ampeares
Impedence
the impedence should be complex conjugate of an equivalent impedence of the network when viewed from the terminals of the load. i.e; Z=R-jx

All telephone exchanges use -48V DC Power supply. The negative potential is used to prevent electrolysis deposition at Battery terminals. Telephone normally work with about 30ma current driving a line impedence of about 1600 ohms (to drive about 5KM distance). Hence 30ma*1600 ohms=48 volts.
You can use an in-line coupler to extend a telephone line.
A lamp can be run by power from a telephone line.
DSL (Digital Subscriber Line) A telephone line that carries digital data fromend to end, and can be leased from the telephone company
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.
No the British Telephone line is not accessible from America. In order for it to work in America it has to be a 1 800 number. The British Telephone line is not a 1 800 number.
No Not really sure what you are looking for in an answer but: A mobile telephone is a telephone, your Telephone connected to a land line is also a Telephone.
The first transcontinental telephone line was joined at Wendover, Utah, in 1915
First long-distance telephone line was created in 1877.
a one line telephone means 1 person can talk at a time and a 2 line telephone means 2 separate people can talk at the same time in the same house
