Study Notes

Types of Electric Circuits

Electric circuits are complete loops allowing electron flow from a voltage or current source.
Two main types: series circuits and parallel circuits.

Series Circuits

All components, including the battery, are connected in a single continuous loop.
Current remains constant throughout; the same value is measured at any point in the circuit.
Voltage is shared among the components; for example, with a 12-volt battery, three identical bulbs would receive 4 volts each.

Parallel Circuits

Components are connected across separate branches, allowing multiple paths for current flow.
The total current from the battery does not equal the current through each individual bulb; current splits at junctions.
For three branches with a total current of 6 amps, each branch may have 2 amps flowing.
Voltage remains consistent across each branch, with each bulb receiving the full voltage of the battery.

Physics Lab Steps

Required Materials: Battery, three small bulbs, ten wires, ammeter, voltmeter.
First setup: Connect battery, ammeter, and bulbs in series, with a voltmeter measuring one bulb.
Obtain current and voltage measurements, then repeat measuring voltage across each bulb.
Next setup: Connect battery and bulbs in parallel, with the ammeter next to the battery and voltmeter across bulbs.
Record measurements similarly to the series circuit.

Data Analysis

Analyze patterns in voltage and current from the collected data.
In series circuits, observe consistent current flow and shared voltage across components.
In parallel circuits, note how current splits among branches while voltage remains equal across each component.
