एक ज्यावक्रीय (sinusoidal) वोल्टेज का शिखर मान (peak value) क्या होगा जिसका RMS मान 115√2 वोल्ट है?

For an R-L-C series circuit connected to an input signal of 4 Vp-p, 1 kHz periodic sinusoidal AC signal, the voltage drop across the resistor R measured with the help of a CRO displays a sine wave occupying 2 units total height with the volts/div knob set at 1 V. What is the RMS current for the circuit if R = 10 Ω?

In a series circuit containing pure resistance and pure inductance, the current and voltage are expressed as: i(t) = 5 sin(314t + 2π3) A v(t) = 15 sin(314t + 5π6) V What is the magnitude of the impedance of the circuit?
