Question

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/5 ampere when the resistance is 8750 ohms. What is the current when the resistance is 17150 ​ohms?

Answer 1

0.102048 ampere

Explanation:

I α k / R

Current = 1/5 ; R = 8750

What is the current when the resistance is 17150 ​ohms

First obtain the value of k :

I = k/R

I = 1/5 ampere = 0.2 A

0.2 = k / 8750

k = 1750

What is the current when the resistance is 17150 ​ohms

I = 1750 / 17150

I = 0.1020408

I = 0.102048 ampere
