In a series RC circuit, what will the graph of current versus time look like for the condition where the capacitor is initially uncharged at time=0 and then connected to a battery. Explain precisely; you do not need to include a graph.

In the RC circuit shown in figure 1, R₁ = 20, R₂ = 49, V = 12 V and C= 5nF. The circuit has been running for a long time with the switch (S) open. Apply Kirchhoff's Loop Rule to calculate a) the current I while the switch S is still open. b) the charge on the capacitor a long time after the switch S is closed. 2 R₂ S R₁ | | I Figure 1: An RC circuit

A fully charged RC circuit is set up using R = 15.0 Ω and C = 8.20 μF with the switch initially open, as shown in the figure. At a certain time after the switch is closed, the current in the circuit has magnitude 3.00 A and the charge on the capacitor is 30.0 μC. At this time, what is the rate at which energy is being stored in the capacitor (in W)?

A capacitor, C, is (fully) charged by connecting it to a 7 Volt EMF and then is allowed to dischargethrough a 2 Ω resistor as shown in the Figure. What is the current, I, in the circuit (in A) when thestored energy in the capacitor has dropped to 30% of its initial value?
