Answer 1

Answer:

1 and 3

Explanation:

Dry cell is a battery which gives a proper potential difference across the circuit by which current can flow.

Current flows from positive to negative terminal of the battery. Opposite to the flow of electrons.

Now, There are two types of cell galvanic and electrolytic. Galvanic cells convert chemical energy into electrical energy.

And dry cell is galvanic cell as it doesn't hold any electrodes.

In the given figure, the top most and lower most is the two terminals of the battery.

Where the positive terminal is the upper one and negative terminal is lower one.

But in the question there is no arrow pointing towards lower one so the arrow pointing inside the battery is the negative terminal.

NOTE: Positive and negative electrodes should not be confused with positive and negative terminals.

These are some points which will help you to know more--

1.Positive terminal

4.Positive electrode

2. Negative electrode

3. Negative terminal
