Study Notes
Circuit Types and Measurements
- Series Circuits: Current is the same through each load/resistor.
- Parallel Circuits: Voltage remains the same across each load/resistor.
- Adding more loads/resistances to a parallel circuit increases the current.
- Adding more loads/resistances to a parallel circuit decreases the total resistance.
- In a series circuit, the sum of the voltage drops across the loads equals the source voltage.
Multimeter Usage
- Voltage Measurement: A multimeter measures voltage in a parallel connection.
- Current Measurement: A multimeter measures current in a series connection.
- Resistance Measurement: A multimeter typically measures resistance by disconnecting the component from the circuit.
