pls see the attached picture, thank you!A. Theoretical Development. 1. (a) Design an ammeter with three scales: 0-200 µA, 0-2 mA, and 0-10 mA. Use a current sensor rated at 200 μA, 100 mV. What resistance does the instrument insert in the circuit at each scale? (b) Using the same current sensor as in (a), design a voltmeter with two scales: 0-10 V and 0- 100 V. What is the maximum current the instrument draws from the circuit for each scale?
2. A heater uses a filament of resistance 10Ω and operates at a voltage of 120 V. If the efficiency of the heater is 40%, then how many kg of water at 25 temperature can be boiled for 5 minutes? Solve with the full step thank u
Write your response. (300 to 500 words) Discussion: 1. Explain the working of the Incandescent light bulb and how it popularized the use of electricity. 2. Consider what was the impact of the introduction of this technology on human lives in that time period, eg. including a contrast with previous lighting technologies, what was different, what were the benefits, what became possible, any limitations, or disadvantages.
Consider the circuit shown in figure 1. The current through the 6 ohm resistor is 4.0 A in the direction shown. (A) what is the current through the 25.0 ohm resistor? (B) what is the current through the 20.0 ohm resistor?
if possible, please write on paper and upload photo of paper. Other forms of answers do not show for me. A 100 W lightbulb is plugged into a standard 120 V outlet. How much does it cost per month (30 days) to leave the light turned on continuosly? Assume electrical energy costs 8.5 cents /kWh. (Enter dollars with no unit) What is the resistance of the bulb? What is the current in the bulb?
Hello again. so now working on problem 24.16 for university of physics. The question goes: Consider the system of capacitors shown in (Figure 1). Figure 1 of 1 Part A Find the equivalent capacitance between bb and cc. Express your answer in picofarads. The figure says this to me: An open circuit includes 3 capacitors. From the top point labeled'A' and gowing down to the bottom point labeled C, one 15-pico Farad capacitor and a parrellel connection of a 9.0-picoFarad and an 11-picofarad capacitors are connected in series. Point B is located on the circuit just below the 15-picofarad capacitor. THAT IS WHAT IT TELLS ME. I will attempt to take a screen shot but have no clue on how to get a good one for you if it turns out bad. Sry just need help thanks if you can help instead of just getting rejected like everything else.
if possible, please write on paper and upload photo of paper. Other forms of answers do not show for me. A common flashlight bulb is rated at 0.300 A and 2.70 V (the values of the current and voltage under operating conditions). If the resistance of the bulb filament at room temperature (20°C) is 2.20 Ω, what is the temperature of the filament, in degrees Celcius (degC), when the bulb is on? The filament is made of tungsten.
Q3 : If you connect a voltmeter across the power supply what will be its reading if (a)the circuit is open, (b) the the circuit is closed, and why ?
I attached the picture of the question, but just in case it is hard to read here it is typed out! Also, I need the answers correct to 4 decimal places. Thank you!! The figure shows how a bleeder resistor is used to discharge a capacitor after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock. The resistor has a resistance of 302 kΩ. a. What is the time constant? (in s) b. How long will it take to reduce the voltage on the capacitor to 1.0% of its full value once discharge begins? (in s) c. If the capacitor is charged to a voltage ?0 through a 120 Ω resistance, calculate the time it takes to rise to 0.9?0 (This is close to two time constants.) (in ms)
1. Why is an electromotive force not a “force”? Justify your answer. 2. Are electromotive force and voltage the same? Justify your answer. 3. A battery contains an emf of 20.0 V. Determine the current flowing the circuit once it is connected to a 30.50 Ω load if the internal resistance of the emf is equal to 0.234 Ω. 4. A battery has an emf of 12V. When a load resistance of 4 Ω is connected to the battery terminals; a current of 2 amperes flows through it. Calculate the internal resistance of this battery. NOTE: Derive the formula of emf to get the internal resistance.
With the switch in the circuit of Figure 27.6a open, there is no current in R2. There is current in R1, however, and it is measured with the ammeter at the right side of the circuit. If the switch is closed (Fig. 27.6b), there is current in R2. What happens to the reading on the ammeter when the switch is closed? (a) The reading increases. (b) The reading decreases. (c) The reading does not change. Figure 27.6 (Quick Quiz 27.3) What happens when the switch is closed?
