The switch in the circuit shown in (Figure 1) has been closed for a long time, and the current through the battery and the charge on the capacitor are no longer changing. At t = 0 the switch is opened. Determine the following in terms of R, C, E, and t: (a) the initial current through the battery; (b) the initial charge on the capacitor; (c) the power being delivered to the second (vertical) resistor the moment after the switch is opened; (d) the time it takes the charge on the capacitor to fall to half of its original value after the switch is opened. Part C Write down Ohm's law for resistance R that has voltage V and current I. Enter your answer as the expression for resistance.

My homework asks : rest is given in the question. Can you help with my homework?   In the circuit in the figure, two identical parallel metallic plates, with identical etallic arcIt has been connected to 100 V battery. Switch on position, plates unloaded,the gap between them is d = 4 mm and the surface of one plate is 1778 m2.When the switch is turned off, the distance between the plates is reduced by 0.5 times. EachWhat is the spring constant of a spring in units of Newton / meter? Eo = 9 x 10-12 C2 / Nm2

The circuit shown in the figure consists of ideal batteries ?1 =20V and ?2 =20V, resistors ? =600Ω, ?1 =600Ω and initially uncharged two capacitors with capacitances ?1 = ?2 =10mF. The circuit is completed when switch S is closed at time t=0. Use the loop rules and the relationship between the charging current i and the charge q of the capacitors a) to obtain a differential equation that allows you to determine how the charge q of thecapacitors varies with time.b) What are the capacitor charges if the switch S is closed for a long time?c) Find the current through the battery ?1 at time t = 3 s after the switch closes.
