Lets start off with an easy question!

There is a 9 volt battery which electrons are flowing through a 3 Ohm resistor. What is the Current?

A current runs through a wire such that it generates a magnetic field. The magnetic field is in the clockwise direction in the plane of your computer screen. What is the direction of the current?

A circuit has a 9-volt battery and a 4-ohm, 6-ohm, and 10-ohm resistor, all in series. What is the total power dissipated in the circuit?

Since no one is posting any questions:

1) Which law is analogous to Newton's Third Law and states that the direction of an induced current always opposes the magnetic field that produces it?

2) What is one assumption of an ideal operational amplifier?

3) Write the equation for the resistance of a wire, given resistivity, the length and cross-sectional area of the wire.

4) Define eddy currents.
