Question

Wjat happens to the current when it reaches the parallel branches (point X)

Answer 1

Answer:

Assume the values of all of the N resistors are of equal resistance value. Your equivalent total resistance is given by,

1RT=NR yielding,

RT=RN

So if you increase the value of N by adding additional parallel branches you effectively decrease the total resistance in the circuit. This of course results in an increase in total current flowing through the ideal source.

Answer 2

Answer:

mark me as Brainliest

Explanation:

case1

when direction of current passes through two parallel wires is in same direction ,

than wires tries to repel each other

because of magnetic field around the wire

which are opposite (for one wire it move

from north to south & for another wire

with respect to first wire it is from South

to north)

case2

when direction of current is opposite

than they will attract each other by similar reason , given in first case

diagram is given for both cases
