Unformatted text preview: CLASS PROBLEM: If a D‐cell battery supplies 2W of power to a small bulb, then find (a) the current through the bulb, and (b) the resistance of the bulb. CLASS PROBLEM: Consider the circuit depicted below. (a) What is the total current supplied to the resistors (the current that leaves the power source)? (b) How much power is consumed by the resistors? TIPS: 1. Combine adjacent series resistors. 2. Compute the equivalent resistance of each “bank” of parallel resistors. 3. Repeat steps 1 and 2 above until Req is found. ...
