Series Circuit
Single loop circuit with one current path.
Parallel Circuit
Multiple loops allowing multiple current paths.
Current in Series
Same current flows through all components.
Current in Parallel
Current splits at junctions but total remains constant.
Potential Difference in Series
Voltage shared among components in the circuit.
Potential Difference in Parallel
Same voltage across each branch of the circuit.
Resistance in Series
Total resistance increases with added resistors.
Resistance in Parallel
Total resistance decreases when adding resistors.
Resistance Calculation
Resistance calculated using R = V/I.
Independent Variable
Number of resistors in the circuit.
Dependent Variable
Total resistance measured in the circuit.
Control Variables
Voltage and type of resistors must remain constant.
Ammeter
Measures current in a circuit.
Voltmeter
Measures voltage across components.
Power Supply
Provides electrical energy to the circuit.
Connecting Wires
Conduct electricity between circuit components.
Investigating Resistance
Experimenting with resistors in series and parallel.
Total Resistance in Series
