Current electricity?

Question

when a resistaence is connected parallely to a zero resistance wire it is said that current flows through zero resistance wire but when two or more resistors are connected parallerly current distributes. Why current does not flows through least resistance wire?

Answer 1

Assume point A and point B.three resistances are connected between Point A and Point B.Resistance 1 say 0 ohms.Resistance 2 say 10 ohms and resistance 3 say 20 ohms.

when all the 3 resistances are connected the current will pass thru  in all the 3 paths, when there is a potential difference between point A and Point B..But in this case once o resistance connected between Point A and Point B, there will not be any potential difference , therefore there will not be any current flow in other resistances.

Answer 2

It does!

Answer 3

The incresed quantity of current will flow through the least resistance path only.But as you said,zero resistance (there is no zero resistance wire invented so far,may be in negligible resistance or in micro ohms) connected across a source means it is short circuiting the voltage.Depends upon the source impedence the short circuit current will flow.If the wire is not able to withstand that current it will blow.As per the ohm's law the Current is inversly proportional to resistance at constant temperature.

so don't get confused,the current will definitly flow through the least resistance path.

Answer 4

Who told you that? Hehe :-) Of course current will flow more through the least resistance. Do you know about Ohm's Law? It states that resistance is inversely proportional with current and directly proportional with voltage (R=V/I). So the lesser the resistance, the greater the current.

Answer 5

this is because the current is the rate of flow of electrons and resistance is the hinderence in the flow of electrons , naturally more electrons will flow through a path that will offer less resistance and hence their rate of flow i.e current will be more through the less resistive path ............

Answer 6

It does.  Technically you can never get to zero ohms.  There will always be some resistance in the conductor.

The shorting wire might be 0.0001 Ω or less.  There is special equipment to measure the micro-ohms across devices such as switches, circuit breakers and fuses

If you run the numbers, the current will be split between your resistor and the shorting wire.  However the resistance of the shorting wire is so small that most of the current flows throught it.

Answer 7

there is nothing called zero resistance .

R=V/I

so when the resistance is zero current is infinite which is not possible in real time ok.
