This document discusses circuit combinations and components. It defines series and parallel combinations, noting that series combinations connect all devices in a circuit through series connections, while parallel combinations connect through parallel connections. The document also defines resistance as a measure of opposition to current flow and capacitors as devices that store electric charge. It provides formulas for calculating total resistance and capacitance in series and parallel combinations.

3. 1.Series Combination : When all the
devices in a circuit are connected by series
connections, then the circuit is referred to as
a series combination.
2. Parallel Combination : When all the
devices in a circuit are connected by parallel
connections, then the circuit is referred to as
a parallel combination.
Series & Parallel .

4.  Resistans : Resistance is a measure of the
opposition to current flow in an electrical circuit
 Capacitor :
A device used to store an electric charge

5. Solution :
Total resistance
R = R1 + R2 + R3
Series Combination of Resistance

6. Solution :
Total Capacitor
1/C = 1/C1 + 1/C2 + 1/C3
Series Combination of Capacitor

7. Solution :
Total resistance
1/R = 1/R1 + 1/R2 + 1/R3
Parallel Combination of Resistance

8. Solution :
Total Capacitor
C = C1 + C2 + C3
Parallel Combination of Capacitor
