Set the variables to obtain and and observe which waveform is leading or lagging and by how many degrees.
\(\theta = \theta_v-\theta_i= \frac{ \text{phase shift (no. of div.)} }{ \text{period (no. of div.)} } \times 360= \) ?
\(i(t)\) lags \(v(t)\) by ?degrees or \(v(t)\) leads \(i(t)\) by ?degrees.
