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.

Is the sum of the potential differences equal to the voltage applied across them?
Yes for a closed circuit
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
What does kirchoff's law of voltage the algebriac sum ofm all the voltage in a series curcuit is equal to?
Zero. The sum of the voltage drops across all loads plus the voltage rises due to sources in a complete circuit must equal zero.
What would be the voltage drop across two 25 resistors in parallel if the source voltage were equal to 9v?
The voltage would 9V minus any drop in the battery.
Does a drop in the voltage slows the flow of current or reduces the current Also in terms of electrons why does a drop in potential difference increase the voltage for the next resistor in series?
If there is less voltage across a resistor, there will also be less current.As for the second question, I assume you mean two resistors in series. If the voltage or potential difference across one decreases, then the other one must increase, due to Kirchhof's Voltage Law: the total voltage across the two resistors must be equal to the voltage across the battery, which is usually assumed to be constant.AnswerYou can think of voltage drops in terms of a water radiator central heating system. In order to drive water around all the radiators, there must be a difference in pressure across the entire system. But for water to flow through each, individual, radiator, there must also be a difference in pressure across its input and output orifices. The sum of these individual pressure difference must equal the pressure difference across the entire system.If you now equate a pressure difference across an individual radiator with the voltage drop across a resistor, then the sum of the voltage drops across each resistor must equal the voltage across the entire circuit.You should also realise that voltage does not 'slow down' current -it affects its magnitude (in amperes)
Why is the voltage across a battery in a parallel circuit equal to the voltage across each bulb?
The voltage across a battery in a parallel circuit is equal to the voltage across each bulb because Kirchoff's Voltage Law (KVL) states that the signed sum of the voltages going around a series circuit adds up to zero. Each section of the parallel circuit, i.e. the battery and one bulb, constitutes a series circuit. By KVL, the voltage across the battery must be equal and opposite to the voltage across the bulb. Another way of thinking about this is to consider that the conductors joining the battery and bulbs effectively have zero ohms resistance. By Ohm's law, this means the voltage across the conductor is zero, which means the voltage across the bulb must be equal to the voltage across the battery and, of course, the same applies for all of the bulbs.
What will be the resultant voltage across different voltage points connected in parallel?
The voltages appearing across each branch of a parallel circuit will be equal to the supply voltage.
When the voltmeter is connected across the open in the circuit the meter will indicate a voltage equal to the?
The source voltage.
How are circuits connected when you are using more than one battery?
The batteries can be connected in parallel or in series. In parallel, good batteries of the same voltage will have a total voltage across them equal to the voltage across one of them. Those batteries in series will have a total voltage equal to the sum of the voltage of each of the batteries.
Why is the peak voltage not exactly equal to the peak voltage of the alernating voltage and by how much it differ?
If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
What is total voltage in a series circuits?
In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.
How much voltage is there across a silicon diode when it is forward biased?
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
The voltage across a short circuit is equal to?
zero? the supply voltage? the supply voltage minus the individual coltage drops? the sum of the individual voltage drops? which one?
Is the sum of the potential differences equal to the voltage applied across them?
Yes for a closed circuit
How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
How is the voltage drop across each resistance of series combination related to the correspoding resistance?
The voltage across each series component is proportional to its resistance, and their sum is equal to the voltage between the ends of the complete series string.
What does kirchoff's law of voltage the algebriac sum ofm all the voltage in a series curcuit is equal to?
Zero. The sum of the voltage drops across all loads plus the voltage rises due to sources in a complete circuit must equal zero.
