Consider the sinusoidal voltage and current for an inductor. If you are given the phase angle of the voltage, the phase angle of the current will be: a) The same as the voltage phase angle b) 90°more than the voltage phase angle c) 90° less than the voltage phase angle d) Dependent on the inductance

QUESTION 9 A voltage of 47V RMS is applied across a real inductor. The current through the inductor is measured to be 29mA RMS and the phase angle between the voltage and current is measured to be 84.7. Determine the internal resistance of the inductor.

An electrical circuit with a sinusoidal voltage source, a resistor, and a capacitor all connected in series. The voltage across the capacitor: Select one: a. Leads the current in the capacitor by exactly 90o b. Is in phase with the sinusoidal voltage source c. Is in phase with the voltage across the resistor d. Leads the current in the circuit by 90o e. Lags the current in the circuit by 90o

3. (a) (b) An emf, E = 12 V, is wired to a solenoid with self-inductance, L= 0.44 H, two resistors, R₁ = 162, and R₂ = 92, and a two-way switch as shown in the diagram. You first set the switch to position a ... How much energy will be stored in the inductor a long time after you set the switch to position a? L 000 R₁ S R₂ a E You move the switch to position b, starting over at t = 0. Calculate the current through, and voltage across, the inductor immediately after you move the switch from a to b.
