B. Explain how to determine the equivalence resistances of these light bulb networks and state whether they obey ohms law with vivid explanation.
AN (5)
c.
Determine with clear explanations which light bulb(s) will glow brightly, and which light
bulb(s) will glow dimly (assuming all light bulbs are identical). Also explain why bulbs Ä"
and "C" will become dimmer (less bright) if the filament in bulb "D" fails open.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
