In the circuit shown in the figure, a $5\ \text{V}$ battery drives current through a $1\ \text{k}\Omega$ resistor and two diodes in series, both forward biased. One is a silicon diode, with a forward voltage drop of $0.7\ \text{V}$, and the other is a germanium diode, with a forward drop of $0.3\ \text{V}$. The current in the circuit is
