In a galvenic cell the direction of current is:

Options

A. anode to cathode
B. cathode to anode
C. `Zn` rod to `Cu` rod
D. Depend on concentration of `ZnSO_(4) and CuSO_(4)

Answer

To determine the direction of current in a galvanic cell, we can follow these steps:

### Step 1: Understand the Components of a Galvanic Cell
A galvanic cell consists of two electrodes: the anode and the cathode. The anode is where oxidation occurs, and the cathode is where reduction takes place.

**Hint:** Remember that oxidation is the loss of electrons, while reduction is the gain of electrons.

### Step 2: Identify the Flow of Electrons
In a galvanic cell, electrons flow from the anode to the cathode. This is because the anode, where oxidation occurs, releases electrons that travel through the external circuit to the cathode.

**Hint:** Electrons move from negative to positive, which means they flow from the anode (negative) to the cathode (positive).

### Step 3: Determine the Direction of Current
By convention, the direction of electric current is defined as the direction of positive charge flow. Since electrons are negatively charged and flow from the anode to the cathode, the current flows in the opposite direction—from the cathode to the anode.

**Hint:** Current is defined as the flow of positive charge, which is opposite to the flow of electrons.

### Step 4: Conclusion
Therefore, in a galvanic cell, the direction of current is from the anode to the cathode.

**Final Answer:** The direction of current in a galvanic cell is from anode to cathode.
