The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 50 amps when the resistances is 20 ohms. What is the current when the resistance is 60 ohms?

• algebra -

I = k/R
50 = k/20, so k = 1000, making

I = 1000/R
I(60) = 1000/60 = 16.67

• algebra -

if y varies directly as x and y = 9 when x =2 find when x =10

• algebra -

E = I*R = 50 * 20 = 1000 Volts = Supply
voltage.

I = E/R = 1000/60 = 16.67 Amps.
