Question

Dry cell convert chemical energy into electrical energy ? Explain

Answer 1

There area unit many alternative forms of batteries, however all have 3 basic components: positive conductor (cathode, or "positive terminal"), negative conductor (anode or "negative terminal"), and solution.

When the positive and negative terminals area unit connected in order that electrons (electricity) will flow between them (usually by a wire), chemical reactions occur at the Compare electric plans. These reactions unleash excess electrons at the anode that flow to the cathode.

The chemical reactions occur between the solution and therefore the cathode and between the solution and therefore the anode. differing kinds of batteries use totally different materials for the these 3 parts.

Disposable batteries (batteries that cannot be recharged) work till the reactive chemistry of the electrodes and electrolytes is exhausted.

In a battery that's re-chargeable, electricity are often applied to run the method in reverse, restoring the properties of the materials in order that electricity-generating reactions can once more recur. automobile batteries area unit Associate in Nursing example of re-chargeable batteries.

Batteries with a liquid solution area unit referred to as "wet cell." Lead-acid batteries (typical automobile battery) area unit galvanic cell. Batteries with a solid solution area unit referred to as "dry cell." alkaline batteries used round the house area unit samples of Leclanche cell.

Batteries build energy transportable. In effect, they store electricity which will be delivered on demand, once and wherever it's required.
