What is the rms value for a sine wave oscillating between a -12mA and 12mA?
8.49mA
How much current will flow in a circuit with a 12 VDC source connected to a 1K load?
In a 12VDC circuit with a 1K load, there will be 12ma of current. (Ohm's law: Volts = Amps * Ohms, so Amps = Volts / Ohms.)
A flow transmitter range is 0 to 2500mmH2o How many Milliamperes on 1250mmH2o?
Your total milliamp range is 4 to 20 milliamps. 4 Ma being 0mmH2o and 20 Ma being 2500mmH2o. So 1250mmH2o is 50% which is equivalent to 12Ma signal.
How do you calibrate control valve?
By using calibrator we can easily calibrate, just we need a air line having pressure of 6 kg as input of control valve. for example : 4mA control valve in close postion 8mA 25% open 12mA 50% 16mA 75% 20mA 100%
What is Kirchhoff's law?
Kirchhoffs Laws are statements about circuits. There are two laws ; 1) The total current entering any point in a closed circuit equals the total current leaving that point. 2) The sum of the voltage changes around any closed path is zero. These "Laws" are a consequence of the more fundamental laws of conservation of charge and conservation of energy.
What is analog transmitter?
a device used to convert a process measurement (i.e. temp, pressure, level) to an analog value which is typically 4-20 mA of electrical current. For instance you need to measure the temperature of water in a pipe. An RTD or a thermocouple will be attached in a way that it can sense the temp. The transmitter will read the temp from which ever you use and convert it into milliamps. So if the range of the transmitter is 0-100 degrees F at 0 degrees the transmitter will output 4mA at 100 degrees it will output 20mA. also 50 dgrees would be 12mA.
What is the Cost of pneumatic control valve product?
Pneumatic process control valves are used in process industries to control the flow of fluid by using pneumatic actuators. It requires 4.5 to 6 Kg/sq. cm of pressure to operate the valve. Control room sends electrical signals of 4-20 ma to field where I/P converter converts these electrical signals into pneumatic signals. Actuators use these signals to operate the valve. Actuators moves the stem up and down depending upon input signals and control the valve opening. 4ma- 0% opening 8ma- 25% opening 12ma- 50% opening 16ma- 75% opening 20ma- 100% opening
How does electricity flow within electric circuits?
electrical charges flow in a series circuit buy a power source and a load
How do the 538 electoral votes get divided among the states?
The number of electors a state is entitled to appoint is equal to the total number of voting members in both Houses of Congress to which the state will be entitled on the next Inauguration Day. The District of Columbia, which has no voting membership in Congress, is entitled to appoint three electors.Each state is entitled to two Senators and at least one Representative. Therefore, each state is entitled to appoint at least three electors. The maximum total number of electors is equal to the total number of House seats (435) plus the total number of Senate seats (100) plus the three from the District of Columbia (435 + 100 + 3 = 538).The number of Representatives to which each state is entitled is redetermined after every U.S. Census and is roughly proportional to the number of people who consider the state their permanent residence, including those away in the military, in college, or temporarily working out of state or abroad. That makes each state's House membership 435 times the ratio of the state population to the national population rounded up or down to the next whole number but no less than one.The population of all 50 states as counted in the 2010 U.S. Census was 308,143,815. The 50 states are listed below in order by population. After each state abbreviation is...the state's 2010 U.S. Census population, followed bythe ratio of the state population to 308,143,815, followed by435 times the previous ratio, followed bythe state's actual number of House seats from January 2013 until January 2023, followed bythe number of electors the state can appoint in 2012, 2016 and 2020 (the previous number plus two).CA - 37253956 - 12.090% - 52.59 - 53 - 55TX - 25145561 - 8.160% - 35.50 - 36 - 38NY - 19378102 - 6.289% - 27.36 - 27 - 29FL - 18801310 - 6.101% - 26.54 - 27 - 29IL - 12830632 - 4.164% - 18.11 - 18 - 20PA - 12702379 - 4.122% - 17.93 - 18 - 20OH - 11536504 - 3.744% - 16.29 - 16 - 18MI - 9883640 - 3.207% - 13.95 - 14 - 16GA - 9687653 - 3.144% - 13.68 - 14 - 16NC - 9535483 - 3.094% - 13.46 - 13 - 15NJ - 8791894 - 2.853% - 12.41 - 12 - 14VA - 8001024 - 2.597% - 11.29 - 11 - 13WA - 6724540 - 2.182% - 9.49 - 10 - 12MA - 6547629 - 2.125% - 9.24 - 9 - 11IN - 6483802 - 2.104% - 9.15 - 9 - 11AZ - 6392017 - 2.074% - 9.02 - 9 - 11TN - 6346105 - 2.059% - 8.96 - 9 - 11MO - 5988927 - 1.944% - 8.45 - 8 - 10MD - 5773552 - 1.874% - 8.15 - 8 - 10WI - 5686986 - 1.846% - 8.03 - 8 - 10MN - 5303925 - 1.721% - 7.49 - 8 - 10CO - 5029196 - 1.632% - 7.10 - 7 - 9AL - 4779736 - 1.551% - 6.75 - 7 - 9SC - 4625364 - 1.501% - 6.53 - 7 - 9LA - 4533372 - 1.471% - 6.40 - 6 - 8KY - 4339367 - 1.408% - 6.13 - 6 - 8OR - 3831074 - 1.243% - 5.41 - 5 - 7OK - 3751351 - 1.217% - 5.30 - 5 - 7CT - 3574097 - 1.160% - 5.05 - 5 - 7IA - 3046355 - 0.989% - 4.30 - 4 - 6MS - 2967297 - 0.963% - 4.19 - 4 - 6AR - 2915918 - 0.946% - 4.12 - 4 - 6KS - 2853118 - 0.926% - 4.03 - 4 - 6UT - 2763885 - 0.897% - 3.90 - 4 - 6NV - 2700551 - 0.876% - 3.81 - 4 - 6NM - 2059179 - 0.668% - 2.91 - 3 - 5WV - 1852994 - 0.601% - 2.62 - 3 - 5NE - 1826341 - 0.593% - 2.58 - 3 - 5ID - 1567582 - 0.509% - 2.21 - 2 - 4HI - 1360301 - 0.441% - 1.92 - 2 - 4ME - 1328361 - 0.431% - 1.88 - 2 - 4NH - 1316470 - 0.427% - 1.86 - 2 - 4RI - 1052567 - 0.342% - 1.49 - 2 - 4MT - 989415 - 0.321% - 1.40 - 1 - 3DE - 897934 - 0.291% - 1.27 - 1 - 3SD - 814180 - 0.264% - 1.15 - 1 - 3AK - 710231 - 0.230% - 1.00 - 1 - 3ND - 672591 - 0.218% - 0.95 - 1 - 3VT - 625741 - 0.203% - 0.88 - 1 - 3WY - 563626 - 0.183% - 0.80 - 1 - 3
