A non-ideal diode is biased with a voltage of $-0.03 \: V$, and a diode current of $I_{1}$ is measured. The thermal voltage is $26 \: mV$ and the ideality factor for the diode is $15/13$. The voltage, in $V$, at which the measured current increases to $1.5 \: I_{1}$ is closest to:
- $-0.02$
- $-0.09$
- $-1.50$
- $-4.50$
