Consider 4 resistors, each 10 ohms. Two are in series - these are followed by the other two resistors which are in parallel. They are connected to a 20 volt battery. Find all currents and voltages.
Draw the magnetic field around: a bar magnet, a current carrying wire, and a coil with current.
A magnetic field is directed into the page. A 0.3 meter long wire carries 2 amperes of current to the left. How strong is the magnetic field if the force on the wire is 5 newtons? Also, which way is the force?
Consider the previous problem. If a proton had been shot to the right in this field, what would the path look like? Draw.
Define and give units for all recently defined quantities.
