What does positive 20mv mean?
Probably 20 millivolts above zero voltage. A really weak voltage.
If a binary input of 10000 to a 5-bit Digital to Analoge converter the output voltage is 20mVwhat would be the out put if binary input was 11000?
My guess is 5'b10000 = 20mV 4'b1000 should be 10 mV (half of the previous one.) 5'b10000 + 4'b1000 = 5'b11000 20mV + 10mV = 30mV Is this correct?

For a binary input of 10000to a 5 bit D A converter the output voltage is 20mV what would be the output if the binary input was 11000?
Some assumptions have to be made. If you assume the left most bit is the highest order bit then 10000 = 16 decimal and 11000 = 24 decimal. Then if you assume a linear analog voltage output 20mV / 16 = XmV / 24 so X = (20 x 24)/16 = 30mV.
Advantages of SMPS over linear power supply?
1.Efficiency is high compared to linear power suplies 2.ripple voltage is very low 20mv. 3.constant regulating voltage is the one of the advantage of smps.

Linear voltage of thermocouple 20mv to 50mv temperature between 750 to 1250 degree Fahrenheit how much voltage will be generated at 1000 degree Fahrenheit?
If 20 mV shows 750 degrees Fahrenheit and 50 mV shows 1250 degrees Fahrenheit then 35 mV will show 1000 degrees Fahrenheit.
At the threshold stimulus sodium ions start to move into the cell or out of cell to bring about the membrane depolarization?
For depolarisation to occur as part of an action potential, +40 mV inside the neuron fibre compared to outside the membrane. For summation after a synapse to determine whether the post-synaptic neuron will fire an action potential, the threshold is +20mV inside the neuron compared to the outside.
What should you do if the pilot won't stay lit on a Teledyne Laars pool heater but will stay on as long as the button on the control unit is pushed down but the flame goes out when released?
This is probably due to a faulty thermocouple. The thermocouple generates a small voltage when hot that is used as a security device that keeps the gas flowing to the pilot. These are relatively inexpensive (UK about �18). You can check if this is the problem by measuring the voltage on the wires coming back from the pilot. When you have the red switch depressed, check the voltage (should be about 30mV). If there's no voltage, then change the thermocouple. The thermocouple will generate up to 50mV in a pilot flame. If it falls below 20mV it should kill the fuel source. It may take a few minutes to generate enough voltage in order to keep the pilot lit, so you may have to depress the button for a minute or more. This would be typical if your unit has been off for an extended period of time.
What is the sensitivity in load cell?
A load cell is an electronic device (transducer) that is used to convert a force into an electrical signal. This conversion is indirect and happens in two stages. Through a mechanical arrangement, the force being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals. A load cell usually consists of four strain gauges in a Wheatstone bridge configuration. Load cells of one or two strain gauges are also available. The electrical signal output is typically in the order of a few millivolts and requires amplification by an instrumentation amplifier before it can be used. The output of the transducer is plugged into an algorithm to calculate the force applied to the transducer.Sensitivity (mV/V) = Full Scale Output (mV) / Excitation Voltage (V)mV = milli VoltV = VoltsStandard sensitivities are 2 mV/V and 3 mV/VExample:For a load cell with 10V excitation has 20 mV full scale output, sensitivity is 20mV / 10V i.e. 2mV/V.
What happens to the membrane potential of a neuron during an action potential?
1. A neurotransmitter (NT) released from another cell (or in some cases the same cell) will diffuse across the synaptic cleft and bind to a recipient receptor. 2. The receptor will then change it's permeability to certain ions in the extracellular fluid, allowing the ions to flux into the cell (the exception here would be pharmacological agents designed to occupy the receptor without leading to a conformation change) 3. The influx of ions will alter the membrane potential. If the NT is inhibitory (e.g. GABA), then the GABA receptor that it binds to will increase its permeability to negatively charged ions (chloride) and thereby lower the local resting membrane potential (which is normally -70mV). If the NT is excitatory (e.g. glutamate) then the glutamte receptor (AMPA or NMDA) will increase its permeability to positively charged ions (sodium) which will increase the resting membrane potential from -70mV. 4. If enough NTs bind then the local membrane potentials will summate - and in the case of excitatory NTs - cause the membrane potential to change (by opening of voltage-gated ion channels) to around 0-20mV leading to an action potential 5. The action potential, which is generated in an 'all or none fashion' at the axon hillock, will then propagate all the way down the axon to the axon terminal causing the release of stored NTs (although not all NTs are stored - e.g. NOS) 6. NTs released from the presynaptic cell will then diffuse across the synaptic cleft and bind their postsynaptic receptor (normally located on a dendrite, although also located on the cell body themselves) and the whole process starts all over again
