Question

If no thermal energy is developed as the charge goes through the battery, then such a battery is called

• A. an ideal battery
• B. an ideal dielectric
• C. an ideal capacitor
• D. an ideal resistor

Hint:

An ideal battery delivers power without any loss as heat. It has no internal resistance.

Answer 1

The Correct Option is A

Step 1: Ideal Battery Definition.
An ideal battery maintains a constant voltage without internal resistance. It dissipates no energy as heat during charge flow, thus generating no thermal energy.
Step 2: Option Analysis.
- Ideal dielectric: A material that does not conduct charge.
- Ideal capacitor: A capacitor without losses or imperfections.
- Ideal resistor: A resistor with zero internal heat dissipation (impossible in reality).
Step 3: Conclusion.
A battery that generates no thermal energy during charge flow is defined as an ideal battery.

Final Answer: \[ \boxed{\text{an ideal battery}} \]
