A simple circuit is made of a power source, a rheostat and an ohmic resistor. The potential difference across the resistor is initially 5.0 ± 0.1 V. A good lab student measures the current across the resistor to be 1.65 ± 5 mA.

a)If the student increases the voltage across the resistor to 9.0 ± 0.1 V, around what value should the measurement of the current across the resistor be (include uncertainties)?
