Increasing current by a factor of 48

[jst]

Homework Statement

Given a circuit with one battery and a single resistor. The circuit has a battery voltage of V, a total current I and resistance R. To increase the current by a factor of 48.0 then by what factor will the voltage need to be increased?

A. 12.0
B. 90.0
C. 65.0
D. 2.00
E. 48.0

Homework Equations

Amps = Volts/Ohms

The Attempt at a Solution

I think it's 48.

Amps = Volts/Ohms
48* Amps = (Volts * x)/Ohms

48*Amps * Ohms = Volts * x

48 * Volts = Volts * x

x = 48


Does this look OK?

Thanks a lot,
