All the lamps from Lamp #1 to Lamp #7 are designed to work with a nominal Voltage Vlamp of 120V and their resistance Rlamp is constant and do not depends on the temperature. Using this information solve the questions below. The Channel 2 has four lamp connected as shown in the Figure 2 and again you want to be sure that will not be a black-out in the middle of the performance. Please determine if the Channel 1 can work using the variable ALPHA from 0% to 100%. Yes/No, justify your answer with your calculations. No justifications – No points

A secondary cell having an end of 2v and internal resistance of 1amp is connected on series with a primary cell having an end of 1.5v and internal resistance of 100amp, the negative terminal of each cell being connected to the positive terminal of the other cell . A voltmeter having a resistance of 50amp is connected to measure the terminal voltage of the cells. Calculate the voltmeter reading and the current in each cell.

A secondary cell having an e.m.f. of 2V and an internal resistance of 1 ohm is connected in serieswith a primary cell having an e.m.f. of 1.5V and an internal resistance of 100 ohm. The negativeterminal of each cell is connected to the positive terminal of the other cell. A voltmeter having aresistance of 50 ohm is connected to measure the terminal voltage of the cells. Calculate the voltmeterreading and the current in each cell.

Please explain correctly in detail. I will upvote. Thank you.

An ammeter is a tool that measures the current (a better name would be V Show Current O Electrons ampmeter) that passes through it. In the circuit simulation you can get Conventional ammeters from the upper right toolbar. Labels Values When current is flowing in through the meter a number value will replace the question mark. Current Votmeter Ammeters Wire Resistivity First make a simple series circuit with a battery, switch, single light bulb and ammeter as shown at right. It's actually not necessary to include the switch but if I left it out then my snapshots would all give away the answers. With the switch closed/current flowing in the circuit, record the current that Current is flowing out of the light bulb and back to the battery. 0.00 A The current is A Now switch the light bulb and the battery so that the ammeter comes before the bulb. Current 0.00 A With the switch closed/current flowing in the circuit, record the current that is flowing out of the battery and into the light…

A 5-ohm resistance is connected in parallel with a 10-ohm resistance. Another set, a 6-ohm and an 8-ohm resistances are also connected in parallel. The two sets are connected in series. What is the equivalent resistance?

Three resistance of 6 0, 12 and 16 Q are connected in star connection. Find its equivalent delta resistance to convert this star in delta. connection

A lead wire and an iron wire are connected in parallel. Their respective specific resistances are in the ratio 49: 24. The former carries 80 percent more current than the latter and the latter is 47 percent longer than the former. Determine the ratio of their cross sectional areas ROUND OFF TO THE NEAREST HUNDRETHS
