PHYS 102 1nd Edition Lecture 12 Outline of Last Lecture I Electrical Energy and Power Outline of Current Lecture II Ohm s Law Current Lecture II Ohm s Law A Ohm s Law Applications 1 A nichrome wire with a radius of 0 791 mm that is to be used on winding a heat coil must carry a current of 9 25 A and a voltage of 120 V Find a Required resistance R I V R 9 25 120 R 120 9 25 R 13 R b Length of the wire to wind the coil R L A 13 150 X 10 8 L r2 13 150 X 10 8 L 0 791 1000 2 7 L 17 m 2 There are two light bulbs one that is 25 W and the other 100 W Which one has higher R P IV I V R Thus P V R V 25 Watt P V2 R R 120 2 25 576 These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute 100 Watt P V2 R R 120 2 100 144 So the 25 Watt light bulb has the higher R Which one has the higher current P IV 25 Watt I P V 25 250 0 1 100 Watt I P V 100 250 0 25 So the 100 Watt light bulb has the higher current
