Two parallel wires carry currents of 20 A and 10 A, respectively, in the opposite direction and have a length of 5 m each. Determine the force between the wires if the distance between the wires is 1.0 cm.

A wire located at the equator points vertically upward from the surface of the Earth. The wire carries a current straight up in a region where the magnetic field vector points due north. The direction of the resulting force on this current is _________.

An electron in an electric field will experience a force acting _____________ the electric field.

Find the equivalent resistance. The upper left terminal connects through the 10 ohm resistor to a top horizontal wire. From that node, one branch goes downward through the 25 ohm resistor to the lower left terminal. The top wire also extends right and then downward through the 8 ohm resistor into a smaller rectangular branch on the lower right. In that lower branch, the 15 ohm resistor is on the lower left side and the 9 ohm resistor is on the right side, with both connected back to the lower wire leading to the lower left terminal.
