This document discusses series and parallel circuits. It defines series circuits as those where components are arranged in sequence, with current passing through each component. Parallel circuits have components arranged in branches, with the same voltage applied across each. The key formulas are provided: for series circuits current is the same through each component but voltage adds up, while for parallel circuits voltage is the same across each branch but currents combine. Examples are given applying the formulas to calculate total resistance in series, parallel and combined series-parallel circuits. Measurement devices like multimeters are also introduced.

3. Series Circuit
Series circuit is the electrical circuit that
arranged in equal or squence

4. Disadventages of series circuit are :
- If one lamp removed (dropped) then other
lights go out.
- Flame lights with each other is not as obvious.
- The farther from the power source increasingly
dim lights
Adventage of series circuit is :
- Saving wiring and switch (cost-effective)

5. Parallel Circuit
Parallel circuit is the electrical circuit that
arranged in rows so form a branch in the circuit

6. Disadventage of parallel electrical circuit is :
- Wasteful cable and switch
Adventages of parallel circuit are :
- If one light goes out the others stay lit.
- Equally bright lights

8. Example to Measuring Resistor
1. Resistor Series Circuit
Answer
Use Formula Of Series Resistor
R Total = R1 + R2 + R3
R Total = 15 + 5 + 30
R Total = 50 Ohm

9. 2. Resistor Parallel Circuit
Answer
Use Formula Of Parallel Resistor
1/R Total = 1/R1 + 1/R2 + 1/R3
1/R Total = 1/15 + 1/15 + 1/30
1/R Total = 2/30 + 2/30 + 1/30
1/R Total = 5/30
R Total = 30/5
R Total = 6 Ohm

10. 3. Resistor Series-Paralel Circuit
Answer
Use Formula Of Series-Parallel Resistor (mix)
R Total = R1 + (R2 // R3)
1/Rp = 1/R2 + 1/R3
1/Rp = 1/30 + 1/30
1/Rp = 2/30
Rp = 30/2
Rp = 15 Ohm
R Total = R1 + Rp
R Total = 15 + 15
R Total = 30 Ohm

11. Measuring with device
