Impedance of voltage source, and tank ckt

[fleem]

Can someone please tell me whether the following statements are wrong or right? this is not homework:

1. Voltage sources, like batteries, have a low impedance (ideally zero)

2. A good car battery's impedance (even with alternating current going through the battery) is typically far less than a few ohms.

3. A tank circuit is driven in parallel and resonates in a series loop.

1. True.
2. True.
3. False.
