Perform the indicated operations if the given changes are made in the indicated examples of this section.

In Example 5, double the values of L and C and then solve the given problem.

Data from Example 5

If R =12.0Ω, L = 0.300 H, C = 250 μF, and ω = 80.0 rad/s, find the impedance and the phase difference between the current and the voltage.

The voltage lags the current (see Fig. 12.28).
