Question

Problem 2 Calculate the electric potential (voltage) for both situations in Problems L,st the point indicated. Problem 3 Your power supply's voltage is 120 Volts. A light bulb draws 14 Watts of power. What are the resistance of the light bulb aad the cuzrent through the light bulb Problem 4 Wrih ? In the circuit shom a. Calculate the voltage difference across each resister b. Suppose both resisters are .75? long. Calculate the electric field in each resister. (Please specify units They coulkd be V/m. V/em, or N/C The numbers may be diferent. ) Problem :3 An electron (chargee) is in circular cebit around a helinn nucleus (rharge 2e, infinite mass) The orbital radius is 2.7 x 10-11 meters He Calculate the orbital speed and its total (kinetic plus potential) energy (e-1.602 × 10-19 C, m-9.11 x 10-31 kg, and k.-9.0 × 10" N m2/Cd.)

Explanation / Answer

Problem 3:

V=120V, P=14W,

P=IV

I=P/V

I=14/120

I= 0.1166 A

R=V/I = 120 /0.1166 = 1029.16 ?
