A resistor of resistance R = 10 Ω is connected in series with an inductor of L = 15 mH. The RL combination is connected to a variable voltage power supply (V = 4.5 V) by a switch as shown.
a. What is the time constant (τ) of the combination in seconds?
b. The power supply is set to maintain a constant voltage of V = 4.5 V and the switch is closed. Calculate the current, in amperes, through the circuit at t = 0.29 ms after the switch is closed.
c. Calculate the current through the circuit, in amperes, after the switch has been closed for a long time.
A 6.0 V battery has been connected to an LR circuit for sufficient time so that a steady current flows through the resistor R=2.2kΩ and inductor L=18mH. At t=0, the battery is removed from the circuit and the current decays exponentially through R. Write the equation for the emf across the inductor as a function of time t. At what time is the emf greatest? What is this maximum value (V)?
A battery of emf E is connected in series with a resistor, an inductor L, and a switch S. A capacitor C is connected in parallel to the inductor. When the switch is left in the closed position for a long time, the potential difference across the
capacitor is zero. The switch is opened and the maximum potential difference across the capacitor is measured to be 140 V. Determine the capacitance of the capacitor if E = 60 V, R = 125 N, and L = 54.0 mH.
