The SI unit of electric charge is the (resistance) (ampere) (ohm) (volt) The energy per unit charge supplied by a battery is its (electric field) (resistance) (current) (voltage) A quantity that is measured in ohms is (electric field) (resistance) (current) (voltage) A quantity that measures the opposition to the flow of charge is (electric field) (resistance) (current) (voltage) 0. Voltage can also be called (potential) (pressure) (work) (energy) 1. If three identical bulbs are connected in parallel, if one bulb...
