Wall that absorbs light and stores energy
A Trombe wall is a massive equator-facing wall that is painted a dark color in order to absorb thermal energy from incident sunlight and covered with a glass on the outside with an insulating air-g. -
Why capacitors are connected in parallel and in series
We can arrange for various capacitors to be connected with each other and the total capacitance of all the capacitors can be defined as the ratio of the total charge held by the capacitor and the total voltage applied in the circuit. This can be represented as, Now we can connect various capacitors in two configurations and the two configurations a. In the figure given below, three capacitors are connected in series with the battery of voltage V. Note that in the figure, opposite charges of equal magnitude flow and get accumulated on the plates of the capacitor. Conservation of charge principles requires that the charge that is accumulated on the plates of the capacitor must be equal in magnit. In the figure given below, three capacitorsC1, C2, and C3 are connected in parallel to a voltage source of potential V. Deriving the equivalent capacitance for this case is relatively simple. Note that the voltage across each capacitor is the same as that of the source since it is directly connected to the source. Thus capacitors have the same char. Example 1: Find the equivalent capacitance for the system of capacitors 3 pF, 5 pF,and 10 pF added in parallel combination. Solution: Example 2: Find the equivalent capacitance for the system of capacitors 2 pF, 2 pF,and 4 pF added in a series combination. Solution: Example 3: Find the equivalent capacitance for the system shown in the figure below. -
