Your brain uses as much power as a ten watt battery. -Helen Brosnan
Neurons do use electricity to communicate. When a neuron communicates, the usual sequence of events is: 1) binding of neurotransmitters to receptors on the cell body (soma) or… dendritic tree; 2) depending on the ligand/receptor in question, the membrane may become more or less permeable to certain ions (such as sodium, potassium, chloride etc), which changes the electrical potential difference across the cell membrane; 3) if the potential difference increases enough, then the cell will 'fire'; sending an 'action potential' (i.e., self-propagating electrical current across the membrane) from its axon hillock all the down to it's synaptic terminal, where it will then release it's neurotransmitters - and the process starts all over over again for recipient cells.
An ammeter is used to measure an electric current. Alternatively, you can use a multimeter , set to an appropriate current range.
About 10-12 watts, so not much. But to use that power would leave next to none to run your body, lol. So in my opinion, unless there is a way to slowly exercise the brain, to …slowly compensate and replace the energy you are trying to harness then it would be a pointless battle. But on the other hand our body generates a lot of thermal, and kinetic energy, which could if done right be upscaled to power lots of awesome things. Andrew R - AKA Extile
Nerve cell signaling is an electro-chemical event. Thus, 'electricity' is used during cell-to-cell communication.
There is no electricity inside of your brain.
\nWhen too much current flows through the fuse, it heats up and melts. Hence, the circuit is broken and the current does not flow through the circuit or the gadget.
If "dead" means brain dead then you've answered your own question, there is no activity left.
It is any current of amplitude sufficient to terminate lifefunctions.
I is the symbol for electric current. It is measured in amps, or amperes (same thing, longer word). An ammeter is used to measure current.
Current is a simple descriptor, I was taught to always use it in school as leaving it off was an error. For instance you cannot say A for AC (Alternating Current) as A is ampe…rage.
Electricity has been found to be the best thing to use for an electric current.
The letter "I" (capital "i"). Lowercase "i" is also used sometimes (for instantaneous current).
unit used for electric current is ampere
ammeter ...the branch in which current is to be measure..ammmeter is connected in series in that branch..
