Two resistors, 18 ohms and 24 ohms, are to be connected in parallel across the certain voltage source. The power dissipated by the 18-ohm resistor was found to be 72 watts. The parallel resistors are then disconnected, only to be reconnected in a series connection. Across what new voltage source should the series combination be connected to preserve the 72-watt dissipation of the 18-ohm resistor? O 84 volts; O The answer cannot be found on the other choices. O 168 volts; O 72 volts;
