An LR circuit can be used as a "phase shifter." Assume that an "input" source voltage V=V0sin(2πft+ϕ) is connected across a series combination of an inductor L = 54 mH and resistor R. The "output" of this circuit is taken across the resistor. If V_0 = 27 V and f = 105 Hz , determine the value of R so that the output voltage VR lags the input voltage V by 30 ∘. Express your answer using two significant figures....

I just did a lab and I can't figure out why the voltage behaves this way. Circuit one: A 1.5 volt battery and a voltmeter V= 1.319V Circuit two: Same as circuit one but there is a bulb parallel with the voltmeter and the voltage drops to 1.156V. Shouldn't the voltage be the same because they are in parallel and how can you use theory or otherwise to explain this? Is it due to resistance decreasing because the bulb abd...
