Two parallel wires carry current in opposite directions, the first at 10a and second at 30a. the wires are separated by 5cm and are 10m long. 1. what is the force on each wire? are the forces acting to push the wires closer or farther apart?
2. sketch the total magnetic field between the wires and outside of the wires.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

reserve is the answer
