Series & Parallel circuit

Series Circuit

- The current flow first through one light bulb(bulb1), then the other(bulb2). The main voltage drop is light bulb1 and light bulb2, at 6.34V and 6.32V each. As a result, the supply voltage is shared by two light bulbs. When the voltage is flowing in series circuit the consumers share the voltage.
- When the amp measures at different parts of the circuit the amp values are all the same at 0.22A. The amp in the individual circuit is higher than the series circuit. Because, the resistance is lower in individual circuit with a light bulb. If the lower resistance is produced in a circuit the amp increases from the ohm's law.
- The watts of two bulbs is decreased because the voltage is shared by two bulbs. Therefore, the brightness of two light bulbs is darker than a bulb of individual circuit.
- When the three bulbs connect in series circuit the supply voltage is shared by three bulbs.The amp is reduced due to one more resistance is produce by the third bulb. The total resistance also increases in three bulbs series circuit and the brightness is darker than two bulbs with lower watts.
- Voltage drop: I can check the voltage consumption each parts in detail.
- Available voltage: The total consumption and remaining voltage are checked from this test.

Parallel circuit 

- The available voltage and the voltage drop are similar in light bulb1 and bulb2. The voltage is not shared in parallel circuit which keeps the individual circuit from each light bulbs.
- The current flows each bulb and the total amp in parallel circuit is higher than individual circuit the total amp value is the sum of the amp of each bulb.
- Total resistance of Parallel circuit
the total resistance value is smaller than the smallest resistance in parallel circuit.
- The watts in parallel circuit is higher than series circuit. Because, the using voltage in each bulb is near supply voltage and the amp is also higher than series circuit. As a result, from this parallel circuit light bulbs consume more energy and show two individual circuit.

Available Voltage

The current flows from positive to negative and this circuit is close circuit when the switch is closed. Available voltage is around 12V between negative terminal before the light bulb and then there are no available voltage after the light bulb because the supply voltage is consumed by the light bulb. The used and remaining voltage are checked by the available voltage at the different points.

Voltage Drop

The voltage drop is measured across the different components of the circuit with using a voltmeter. There are small voltage drop at 0.01V to 0.02V, such as switch, terminal and wire because the resistance is produced from these components and the main voltage drop is from the input to the bulb to the output of the bulb. The light bulb uses supply voltage with a main consumer in this individual circuit.
