Question

The current, I, in an electrical conductor varies inversely as the resistance,R, of the conductor. The current is 5 amperes when the resistance is 882ohms. What is the current when the resistance is 428 ohms? Round youranswer to two decimal places if necessary.

Answer 1

ANSWER:

10.30 A

SOLUTION

I=k/R this is base on the definition of I is inversely proportional to R

we need to find the constant k

5=k/882

k=4410

substitute k and R value to get I

I=4410/428

I=10.30
