When two pointed carbon rods connected to an electric current source touch each other, the resistance at the pointed ends is so high that the rods are heated and begin to glow. When subsequently the rods are separated, they are warm enough for the negatively charged one to easily emit electrons: a discharge is created between the two rods.
The carbon rod is a conductor only and does not undergo reduction. The voltage produced by a fresh dry cell is (1.5 : text{V}), but decreases during use. An alkaline battery is a variation on the zinc-carbon dry cell. The alkaline battery has no carbon rod and uses a paste of zinc metal and potassium hydroxide, instead of a solid metal anode.

If the current is too high it will blow the fuse on the multimeter, or blow up the battery. Wikipedia says the Energiser AA battery has an internal resistance of about 0.15R at room temperature. This gives around 10A current. However, the internal resistance of the multimeter may now have an effect, reducing the current.

Dry cell battery by Wilhelm Hellesen 1890. Many experimenters tried to immobilize the electrolyte of an electrochemical cell to make it more convenient to use. The Zamboni pile of 1812 is a high-voltage dry battery but capable of delivering only minute currents. Various experiments were made with cellulose, sawdust, spun glass, asbestos fibers, and gelatine.
