Two parallel wires have electrical current running through them in opposite directions.
1 answer:
Answer:
D. There is a magnetic force pushing the wires away from one another.
Explanation:
When electric current flows through one wire then it will induce magnetic field now this magnetic field will exert the force on another current carrying wire
Now we know that force between two current carrying wires is given as
so here if two wire have current in same direction then two wires will attract each other
Also when current in wire is anti parallel to each other then the force between two wires is repulsive force
so correct answer will be
D. There is a magnetic force pushing the wires away from one another.

Answer:
They're going to increase the total resistance as
Explanation:
If the resistors are in parallel, the potential difference is the same for each resistor. But the total current is the sum of the currents that pass through each of the resistors. Then
