A transformer with a turns ratio (secondary/primary) of 1:13 is used to step down the voltage from a 120-V wall socket to be used in a battery recharging unit. Part A What is the voltage supplied to the recharger? Express your answer using two significant figures. V = IVE ΑΣΦ ? V

The capacitor in the circuit shown is fully charged by a 24 V battery. The switch is closed at t = 0. At sometime after the switch is closed, the voltage across the capacitor is measured to be 10 V. What is the current in the circuit at this time, in Ampere? C = 3.0 µF, and R = 2.0 02. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Cil

If the switch (S) in the figure is closed for a very long time, what is the charge on the capacitor?  Use an emf of  20 V, R1 = 100 Ω and  C1 = 20 μF.

The capacitor in the circuit shown below is initially uncharged. The switch is closed at t = 0 s. AVbattery = 30 V, C = 3.0 F, and R = 2.0 Q. What is the current in the circuit at t = 7.5 s, in Ampere? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. R HIH
