Question

1. imagine you have a single portable battery that has two outputs, all on a single circuit. what component would be included in the device in order to ensure that the energy of one device is not charging the other device?

• series circuit
• parallel circuit
• diode
• transformer

Explanation:

A diode allows current to flow in only one direction. This prevents energy from one connected device from flowing back and charging the other device, as it blocks reverse current. A series/parallel circuit is a circuit configuration, not a component, and a transformer is used to change voltage levels, not prevent reverse current flow.

Answer:

C. diode
