How does battery generate electric current in a circuit?
sveticcg [70]

Answer:

C. It creates negative electric charges and pushes them into the circuit

Explanation:

A battery has three main parts. The Cathode (Positive), the Electrolytes (energy source), and the Anode (negative). The anode takes energy from the electrolytes and creates more electrons. And because subatomic particles with the same charge don't like being in the same place, they move through the circuit to reach the cathode because opposites attract.

I hope this helps!
