T/F: Current exists in an ideal capacitor only when its voltage is changing True T/F: In a series capacitor circuit, the largest value of capacitance will have the smallest amount of voltage dropped across it. True T/F: In a series capacitor circuit, the largest value of capacitance will have the largest share of total charge on its plates False T/F: Magnetic lines of force never cross one another True T/F: Current flowing through a conductor creates a magnetic fi...
