Question

When a nerve cell depolarizes, charge is transferred across the cell membrane, changing the potential difference. For a typical nerve cell, 9.0pC of charge flows in a time of 0.5ms. What is the average current

Answer 1

Answer:

1.8nA

Explanation:

I = dq/dt

I = 9.0 × 10 ^-12 / 0.5 × 10^-3

I = 1.8 × 10× 10^-8

I = 1.8nA

Answer 2

Answer:

18aN

Explanation:

To calculate the average current, we need to know the the formal for it. The formula for average current is given by;

I = dq/dt

= 9×10^(-12)C÷0.5×10^(-3)S

= 1.8×10^(-9)

= 18aN

Therefore, average current when calculated is gotten as 18aN
