Problema Solution
Electrical current. The current I in an electrical
conductor varies inversely as the resistance R of
the conductor. The current is 1/4 ampere when the
resistance is 3840 ohms. What is the current
when the resistance is 6000 ohms?
Answer provided by our tutors
The current I in an electrical conductor varies inversely as the resistance R of the conductor
I = k/R, where k is constant
The current is 1/4 A when the resistance is 3840 ohms that is
1/4 = k/3840
we solve for k
k = 960

we know that R = 6000 ohms and we need to find I
since I = 960/R we have I = 960/6000 = 0.16 A
when the resistance is 6000 ohms the current is 0.16 ampere.
