Type: MCQ-numerical-Easy-Class 11
If a neuron has a resting potential of -70 mV and during depolarisation the potential difference becomes +30 mV, what is the change in membrane potential?
A
100 mV
B
40 mV
C
30 mV
D
70 mV
Correct Answer
Option A
Detailed Explanation
The change in membrane potential is the difference between the depolarised potential and the resting potential, which is 30 mV - (-70 mV) = 100 mV.
