1. --') (a) A resistor has four color bands brown, orange, yelow, and Gold. What is its resistance? (b) A 60-W/120V light bulb is comected to 120 V. What is its resistance? 2. n (a) A cylindrical conductor has resistance of Re = 402. If we decrease the radius of the conductor by a factor of 2, while keeping the rest fixed, what is the new resistance? (b) A battery with emf of 12 V, with an internal resistance of 7 = 0.5n, is connected in series with this cylindrical conductor (with the radius reduced). What is its terminal voltage (V = E - Ir)?
