Mathematics

5 0

Answer:

Step-by-step explanation:

1000 Ohms

R = 1000

V = 9

I = V / R

I = 9 / 1000

I = 0.009

500000 Ohms

V = 9

I = V/R

R = 500000

I = 9 / 500000

I = 0.000018

Can any negative integer be greater than a positive integer explain
Keith_Richards [23]

No, it is impossible. Intuitively, a negative number sits at the left of 0 on the number line, and a positive number sits at the right of 0 on the number line. And a number x is greater than another number y if x sits at the right of y on the number line. So, every positive number is greater than any negative number.

Also, by definition, a positive number is greater than 0, and a negative number is smaller than zero. So, if x is positive and y is negative, you have

y < 0 < x

and since the relation of order "<" is transitive, this implies

y < x
