Only voltage source and wire?(PLEASE SEE THIS!!) Suppose a voltage source of any value(eg:5V,10V etc) is connected with a wire and thats all about the circuit,nothing else (resistors,bulbs or any kind of loads) is connected with the circuit.Assume that the internal resistance of the wire is totallyzero ,then what is the voltage drop and current at point B?(see the attached figure)Would the current flow become theoretically infinity? and voltage drop is zero?
