Question
A resistor with resistance R and a capacitor with capacitance C are connected in series to an AC voltage source. The time-dependent voltage across the capacitor is given by VC(t)=VC0sin?t.
What is the amplitude VR of the voltage across the resistor? Express your answer in terms of VC0, C, ?, and R.
VR=?

VR=?
Explanation / Answer
VR=Applied Voltage/Resistance(ohm's law)
=VC0sin?t/R
P.S= both the voltage applied and voltage across it is in the same phase across a resistor.so that is why we simply divide by the resistance value usin ohm's law.
