Question

If L, C and R are the self inductance, capacitance and resistance respectively, which of the following does not have the dimension of time?

Options

• RC

• `"L"/"R"`

• `sqrt"LC"`

• `"L"/"C"`

Answer 1

`bb("L"/"C")`

Explanation:

RC and `1/"R"` are time constants.

Where `sqrt"LC"` has a time dimension and is inverse of angular frequency.

Thus, the only choice left is `("L"/"C")`.
