The battery of emf 100 V and a resistor of resistances 10kΩ are joined in series.


The battery of emf $100 \mathrm{~V}$ and a resistor of resistances $10 \mathrm{k} \Omega$ are joined in series. This system is used as a source to supply current to an external resistance $\mathrm{R}$. If $\mathrm{R}$ is not greater than $100 \Omega$, the current through it is constant up to two significant digits. Find its value. This is the basic principle of a constant-current source
