QuickTimeQ and aTIFF (Uncompressed) decompressorare needed to see this picture.Equivalent resistance conceptsFalse:Rcdis always less than or equal to R3. True:Rabis always less than or equal to R1. True:After connecting cand dto a battery,the current through R3always equals the current through R4. True:After connecting aand bto a battery, the voltage across R1always equals the voltage across R2.QuickTimeand aTIFF (Uncompressed) decompressorare needed to see this picture.In the picture below, the two wires carry current i1and i2, respectively, with positive current to the right. The charge q is positive and has velocity v to the right.False:If i2= 0 and i1is greater than zero, then the force on q points into the page. True:If i1= 0 and i2is greater than zero then the force on q is south. True:If v = 0, then the force on q is zero. False:If i2= 0 and i1is greater than zero, thenthe magnetic field near charge q points out of the page.
