What else can I help you with?
Why does a bulb glow when electric passes through it?
The filament in the bulb has resistance. The current flowing through the resistance of bulb causes the filament to dissipate energy in the form of heat and light. The filament is actually glowing white-hot because of the energy it is dissipating, thus giving off light.
What instrument do you use to measure dry bulb and wet bulb temperature?
You would use a sling psychrometer to measure both dry bulb and wet bulb temperature. The dry bulb thermometer measures the air temperature, while the wet bulb thermometer measures the temperature with evaporative cooling considered.
The difference between wet-bulb and dry-bulb temperature is called?
The difference between wet-bulb and dry-bulb temperature is called the Wet-Bulb Depression. It is a measure of air humidity, with a larger depression indicating higher humidity levels.
What is the thin wire inside a bulb called?
It is called a filament and usually made of tungsten steel.
Why is bulb temperature is lower than the dry?
Bulb temperature is typically lower than dry temperature because the bulb thermometer measures the temperature of the air without factoring in the effects of evaporation. The dry bulb temperature, on the other hand, accounts for the cooling effect of evaporation, giving a lower reading than the bulb temperature.
What type of ion channel opens on the synaptic end bulb in response to depolarisation?
Calcium (Ca2+) channels open on the synaptic end bulb in response to depolarization (from the action potential), inducing exocytosis of synaptosomes containing neurotransmitter, resulting in neurotransmitter being released into the synaptic cleft...further propagating the signal to the next neuron or set of neurons.
Where is the synaptic bulb found?
The synaptic bulb is found at the end of axon terminals in neurons. It is the structure responsible for releasing neurotransmitters to communicate with other neurons or target cells at a synapse.
What causes Chrysler 2000 jxi to burn out headlights frequently?
Your headlight is leaking, allowing water to enter the lens. when it is on water will burn out the bulb.
What causes a light bulb not to work?
Bad bulb, no power, no ground.
What does the principle of the wet-bulb and dry-bulb thermometers state?
Evaporation causes cooling.
What causes gas to come out the primer bulb?
A cracked primer bulb. You will need to replace it.
What are causes for water inside of light bulbs?
Water inside light bulbs is typically due to poor sealing or manufacturing defects that allow moisture to enter the bulb. Changes in temperature can also cause condensation to form inside the bulb. In rare cases, it could be caused by a crack or break in the bulb itself.
What is the difference between the axon and axonal terminal and synaptic knob?
The axon is a long, slender projection that carries electrical impulses away from the cell body. The axonal terminal, or synaptic knob, is the end of the axon that forms a synapse with another neuron or target cell. The synaptic knob contains neurotransmitter vesicles that are released into the synapse to communicate with the next cell.
What causes a light bulb to go out?

What is the structure at the end of an axon that produces neurotransmitters?
The axon is a single process extending from the axon hillock, sometimes covered by a fatty layer called a myelin sheath that conducts nerve impulses away from the cell body of the neuron.Distal tips of axons are telodendria, each of which terminates in a synaptic knob.
Name the neuromuscular transmitter that is released at the axon bulb?
The neurotransmitter released at the axon bulb is acetylcholine.
How many bees does it take to change a light bulb?
Only two, as long as the light bulb has a hole, large enough for them to enter!
