Question

A medical imaging device shoots 8 million electrons per second through an Ohmic gas. The electrons are motivated by a 3000 V potential difference. What is the effective resistance of the gas?

Answer 1

Resistance of the gas is given as

`R = 2.34 * 10^(15) Ohm`

Step-by-step explanation:

As we know that number of electrons per second is

`(N)/(t) = 8 * 10^6`

now we have

`i = (N)/(t) e`

`i = 8 * 10^6 (1.6 * 10^(-19))`

`i = 1.28 * 10^(-12)`

now we have

`R = (V)/(i)`

`R = (3000)/(1.28 * 10^(-12))`

`R = 2.34 * 10^(15) Ohm`
