Q1. How many 104 W lightbulbs can you use in a 102 V circuit without tripping a 17 A circuit breaker? (The bulbs are connected in parallel that means that the potential difference across each lightbulb is 102 V.)

Q2. A community plans to build a facility to exchange solar radiation to electrical power. They require 0.7 MW of power, and the system to be installed has an efficiency of 14 percent (that is, 14% of the solar energy incident on surface is converted to electrical energy). What must be the effective area of a perfectly absorbing surface used in such an installation, assuming a constant power per unit area of 1346 W/m^2 in the incident solar radiation?
