Explain how you would use an oscilloscope to measure an alternating potential difference of the order of 10V peak-to-peak. (You may assume that an alternating PD of 5V peak-to-peak is available).What is the RMS value of a peak-to-peak voltage of 10.0V?

Explain each of the following statements, whether true or false:a. The instantaneous voltage across the capacitor lags the current by 90°.b. The instantaneous voltage across the inductor leads the current by 90°.c. The instantaneous voltage across the resistor is in phase with the current.d. The voltages across the resistor, capacitor, and inductor are not in phase.e. The RMS voltage across the combination of the three elements equals the algebraic sum of the RMS voltages across each element separately.
