Question 920335: The current (I) in a wire varies directly as the voltage (v) and inversely as the resistance (r). If the current is 27.5 amps when the voltage is 110 volts and the resistance is 4 ohms, find the current when the voltage is 120 volts and the resistance is 12 ohms. (Round your answer to two decimal places.)

The current (I) in a wire varies directly as the voltage (v) and inversely as the resistance (r).
Ohm's law: I = v/r
If the current is 27.5 amps when the voltage is 110 volts and the resistance is 4 ohms,
:
find the current when the voltage is 120 volts and the resistance is 12 ohms.
I = 120%2F12
I = 10 amps
