$$\mathrm{Because} \\ $$$$\mathrm{Ohm}=\frac{\mathrm{Volt}}{\mathrm{Ampere}} \\ $$$$\Leftrightarrow \\ $$$$\mathrm{Volt}=\mathrm{Ampere}×\mathrm{Ohm} \\ $$$$\Leftrightarrow \\ $$$$\mathrm{Ampere}=\frac{\mathrm{Volt}}{\mathrm{Ohm}} \\ $$$$\mathrm{If}\:\mathrm{you}\:\mathrm{have}\:\mathrm{low}\:\mathrm{to}\:\mathrm{no}\:\mathrm{resistance}\:\mathrm{the}\:\mathrm{current} \\ $$$$\mathrm{becomes}\:\mathrm{very}\:\mathrm{high}\:\mathrm{and}\:\mathrm{you}'\mathrm{ll}\:\mathrm{end}\:\mathrm{with}\:\mathrm{an} \\ $$$$\mathrm{electrical}\:\mathrm{short}.\:\mathrm{Your}\:\mathrm{meter}\:\mathrm{will}\:\mathrm{blow}. \\ $$
