Answer:
1. -30 to -90 mV
2. +60 to +80 mV
3. -84mV
Step-by-step explanation:
In resting neurons, the resting potential ranges from 30 to 90 mV across the membrane. The inside membrane of a neuron is more negative as compared to the outside membrane. Thus, the inner resting potential of neuron varies between -30 to -90 mV.
Equilibrium potential is defined as the potential across the membrane when the net flow is zero. This potential for sodium ion ranges between +60 to +80 mV
The equilibrium potential for K varies from -84mV.
