Question

which type of current flows in only one direction and is produced by a battery? magnetic voltage alternating direct

Explanation:

To solve this, we analyze each option:

• Magnetic: Related to magnetism, not current flow direction from a battery. Eliminate.
• Voltage: Is the potential difference, not a current type. Eliminate.
• Alternating: Changes direction periodically, e.g., from power grids. Not from a battery. Eliminate.
• Direct: Flows in one direction, and batteries produce direct current (DC).

Answer:

direct (the option "direct" is the correct one, corresponding to the description of current flowing in one direction and produced by a battery)
