1. To connect a pair of resistors so that their equivalent resistance will be greater than the resistance of either one, should you connect them in series or in parallel?

2. In the circuit shown, how do the brightnesses of the individual bulbs compare? Which light bulb draws the most current? What will happen if bulb A is unscrewed? If bulb C is unscrewed?
