The current through a 10-ohm lamp energized by two series-opposing ideal batteries is measured to have a magnitude of 1 ampere. Determine the individual EMFs of the two batteries if the magnitude of the current through the same lamp becomes 2 amperes when the batteries become series-aiding. 10 and 20 volts; O 20 and 30 volts; O 15 and 25 volts; O 5 and 15 volts
