I2k = 7mA I 2 k = 7 m A. Steady-state is redrawn in Figure 9.4.4, using a short in place of the inductor, and an open for the capacitor. We are left with a resistance of 2 k Ω Ω in series with the parallel combination of 1 k Ω Ω and 4 k Ω Ω, or 2.8 k Ω Ω in total. Figure 9.4.4 : Steady-state equivalent of the circuit of Figure 9.4.2 .

I have attached the picture of the circuit. I''m trying to figure out the steady state voltages across the 2 resistors and the capacitor. V_s is given to be 10V DC. At steady state in a DC circuit, a capacitor acts as an open. When that happens, we shouldn''t expect any current to flow...

Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity …

Thus, the energy is stored by creating a difference in charge. The capacitor essential made from two metal plates separated by a distance with a material called the dielectric in the between which typically is an insulator material – it does not conduct electricity. When charged (by a battery for example) it stores a charge the plates ...

The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is ...
