Why is The voltage across the empty socket is equal to the line voltage?
all the sockets are always connected in parallel,due to this the voltage across each soket is same. when any socket is open then there is no voltage loss..so the votage is same like line voltage.
Why a lamp cannot run with the telephone line voltage?
A lamp can be run by power from a telephone line.
What two things happen when the number of appliances connected to the multiple socket is increased?
The amperage of the circuit increases and the voltage drop across the appliances will tend to increase.
What is the voltage of telephone line?
I'd say it wouldn't be -40 volt, but in fact 40 volt. I'm guessing you measured it with a multimeter and had your polarity (positive/negative) mixed up when you placed the leads on the telephone line. -------------------------------------------------------------- The nominal voltage between tip and ring on the telephone line is 48 VDC (it is provided by a 24 cell lead acid battery in the central office) but this can be reduced by line drop by as much as 9 VDC depending on how far you are from the central office. Tip is connected to the positive side of the battery and ring is connected to the negative side of the battery. The tip and ring twisted pair is isolated from ground, so either can be used as your multimeter reference as long as you are aware of polarity so the reading of the multimeter will make sense.
Three identical bulbs are connected in parallel across a 12-V battery If one of the bulbs were removed from its socket then the potential difference measured across the empty socket would be?
12V. Every resistor in a parallel circuit shares the same voltage. It is the current that gets divided.
How much voltage is in a socket?
The voltage in a socket can be any voltage that you want. The load that connects into the socket must be stated. Without this information the question can not be answered.
Can Telephone and electricity cable in same socket?
AC and telephone should be in separate boxes.
Why is The voltage across the empty socket is equal to the line voltage?

In North America how much voltage comes out of a normal wall socket?
In North America a nominal voltage of 110 to 120 volts comes out of a normal wall socket.
What is the voltage of a telephone line?
48 VOLTS
How to Replace lamp socket?
1. Unplug from voltage. 2. Remove lamp. 3 Remove socket from stand. 4. Replace old socket with new socket.
What is the voltage required to activate a telephone answering unit connected to a telephone?
48 volts
What voltage can not use to a 110 socket?
Only use 110-120 volt appliances on a 110 volt socket.
Why a lamp cannot run with the telephone line voltage?
A lamp can be run by power from a telephone line.
Bt master socket what is it?
It's the first socket inside your property - that's attached to the line coming in from the telephone pole.
Netgear rangemax wireless modem router connected to the master telephone socket intermittant loss of connection whilst surfing when this happens the ppp light goes out will usually reconnect in 1 min?
if you have intermittent crackle on telephone. I've been told to replace master telephone socket
Why telephone line has negative voltage?
A negative live voltage is used to prevent electroytic corrosion on the copper wires.
