- Find the equivalent inductance as seen from the terminals shown in the figure.arrow_forwardA circuit is comprised of an inductor, a capacitor, a battery and a switch. When a he switch is in position "a", the battery is in series with the capacitor, but the inductor is excluded. When the switch is in position "b", the capacitor and the inductor are in series, but the battery is excluded. Two voltmeters and an ammeter have been added to the circuit, as shown. Vc VL Vo > A 8% Part (a) Initially the switch is moved to position "a" where it remains until the capacitor attains its maximum charge. Enter an expression for the maximum charge on the capacitor. Inax = - A 8% Part (b) Once the capacitor is fully charged, the switch is moved from position "a" to position "b". Let q represent the charge on the capacitor, and et I represent the current measured by the ammeter at any given time after the switch is moved to position "b".

- The circuit in Figure has been connected for a long time. If the battery is disconnected, how does it take the capacitor to discharge to 1/20 of its initial voltage? Take R₁ = 2.00 Q, R₂=4.00 Q, R3-7.00 Q, R4 = 2.00 Q and C= 5.00 uF and ε = 14.0 V. (Your result must be in us. Include 2 digit after the decimal point and maximum of 2% of error is accepted in your answer.) E R₂ R₂ BAarrow_forwardIn the figure the potential difference V of the battery is 10V. Each capacitor C has a value C = 10 μF. What is the charge on the capacitor C1.arrow_forwardIn the diagram below, the switch S has been closed for a long time. A) What is the output voltage Vout? What is the charge on the capacitor? b) The switch is opened, so the output voltage increases. What is the time constant that describes the charging of the capacitor in terms of R and C? c) When Vout reaches 10 V, the switch closes and the capacitor begins to discharge. What is the time constant that describes the discharging in terms of R and C? Hint: Apply Kirchhoff's Rules to both loops and the sum of the currents at the junction above the capacitor in the diagram, and use I=dq/dt. If the switch opens when Vout reaches a lower value, say 5V, the capacitor will charge again, and thus one can cycle the voltage with a time constant determined by the circuit: this demonstrates the principle of operation of an electronic timer. 4R S 15 V Vout Rarrow_forward
