Ejercicio 1:¿cual es la resistencia de un circuito por el que circula una corriente eléctrica de 2A con una tensión de 12v

Calcula el voltaje existente entre los extremos de una resistencia de 100 Ω por la que circula 0,1 A

V=A×R

V=0.1 A×100Ω

V=10 Voltios

bueno eso me sale XD ojala te ayude :D

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.

it would lead to upper respiratory infections and pneumonia.
