Two 100-W light bulbs of fixed resistance are to be connected to an ideal 120-V source. What are the current, potential difference, and dissipated power for each bulb when they are connected
 
  (a) in parallel (the normal arrangement)?
  (b) in series?

Question 2

A small 175-g ball on the end of a light string is revolving uniformly on a frictionless surface in a horizontal circle of diameter 1.0 m.
 
  The ball makes 2.0 revolutions every 1.0 s.
  (a) What are the magnitude and direction of the acceleration of the ball?
  (b) Find the tension in the string.

Answer to Question 1

(a) 0.83 A in each; 120 V for each; 100 W in each (200 W total)
(b) 0.42 A in each; 60 V for each; 25 W in each (50 W total)

Answer to Question 2

(a) 79.0 m/s2 toward the center of the circle (b) 13.8 N
