Two electric bulbs, rated at (25 W, 220 V) and (100 W,220 V ) are connected in seriees across a 220 V voltage source. If the 25 W and 100 W bulbs draw powers P1 and P2 respectively, then :
P1 = 16 W , P2 = 4 W
P1 = 4 W , P2 = 16 W
P1 = 16 W , P2 = 9 W
P1 = 9 W , P2 = 16 W
Power dissipiated in external resistance -
-
& are in series
P1 = 16 W , P2 = 4 W
Option 2)P1 = 4 W , P2 = 16 W
Option 3)P1 = 16 W , P2 = 9 W
Option 4)P1 = 9 W , P2 = 16 W
