1.A single light bulb is connected to a 12 V battery. The light bulb uses 55 W of power (which is about what a car’s headlight uses). (a) What is the current flowing out of the high-voltage (+) end of the battery? (b) What is the current flowing into the low-voltage (-) end of the battery? (c) The battery has a sticker on it that says “This 12V battery contains 50 Amp-hours.” This indicates Amps × hours that the battery...

1. The filament of a standard 100-W light bulb has a resistance of about 100 ohms. For this laboratory the glass of the light bulb is unfrosted, so that the filament can be viewed directly. The light bulb is connected to a variable AC voltage source (a Variac), which can deliver up to 140 volts AC. When the voltage is low, about 20 volts, the filament is a dull, red color. When the voltage is high, 100 V, how does...

When you put your light bulb in a circuit, it may not light up. Which measurement can you make to show that the lightbulb is still an active element in the circuit, even if its not lighting up. Describe what you expect the measurement to read if the lightbulb isn’t working compared with if it is working, but just not hot enough to see as light.

1. Suppose you have a 12-V battery, two light bulbs, and some wires that you can use to connect them. (a) Draw a diagram showing the battery wired to the two light bulbs in the series configuration. Wires can be shown by lines, battery by a rectangle, and light bulb by some simple shape. (5 pts) (b) Draw a diagram showing the battery wired to the two light bulbs in the parallel configuration. (5 pts) 2. The headlight in a...

Question 9 - M2 (11 marks) An incandescent light bulb is basically a resistor in an electrical circuit. The Tungsten wire filament acts as the resistor. Consider you connect an 60 Watt bulb to a 240V mains household electricity supply. 9.1) (4 marks) If the Tungsten filament is constrained to be of 15um diameter, how long does the Tungsten wire need to be to make the filament?...

question 7 and 8
Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...

1. Name at least 3 ways you can control the amount of light that reaches the ocular lens. 2. Define resolution. What is the limit of resolution for the light microscope? 3. What effect does the wavelength of light used have on resolution? 4. If you view a bacterial smear under the oil immersion lens, but forget to add oil, will the image still be just about as clear as if you had added the oil. 5. Define parfocal. 6....
