Problema Solution
the current I in an electrical conductor varies inversely as the resistance R of the conductor
the current is 7 amperes when the resistance is 950 ohms
what is the current when the resistance is 550 ohms?
Answer provided by our tutors
I1=7 amp; R1=950 ohms;
I2=?; R2=550 ohms;
I2=I1(R1/R2)
=7(950/550)=7(19/11)
So I2=12.09 amp
So the current when the resistance is 550 ohm is 12.09 amp
