Source: Laboratory of Dr. B. Jill Venton - University of Virginia Calibration curves are used to understand the instrumental response to an analyte and predict the concentration in an unknown sample. Generally, a set of standard samples are made at various concentrations with a range than includes the unknown of interest and the instrumental response at each concentration is recorded. For more accuracy and to understand the error, the response at each concentration can be repeated so an error...

RC Circuits: Discharging A Capacitor

2025
One of the applications of an RC circuit is the relaxation oscillator. The relaxation oscillator comprises a voltage source, a capacitor, a resistor, and a neon lamp. The lamp acts like an open circuit (infinite resistance) until the potential difference across the neon lamp reaches a specific voltage. At that voltage, the lamp acts like a short circuit (zero resistance), and the capacitor discharges through the neon lamp and produces light. Once the capacitor is fully discharged through the...

Heating and Cooling Curves

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves. For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...
FAQs
Internal resistance causes part of the battery’s voltage to be lost when current flows through the cell. As load demand increases, this effect can produce a steeper voltage decline, even while stored energy remains available. Engineers examine this response to distinguish changes caused by operating conditions from broader limitations in the battery’s electrochemical performance.
Discharge rate changes how quickly the battery must deliver electrons through the external circuit. Greater current demand can accelerate voltage decline and alter the capacity available before the cutoff point. Comparing curves at different rates therefore shows how strongly a battery’s performance depends on load, which helps engineers match a cell to its intended operating requirements.
Temperature is one of the operating conditions that shapes both voltage decline and the capacity delivered during discharge. A curve measured at one temperature may not represent performance under another condition. Including temperature when analyzing results helps engineers separate intrinsic battery behavior from environmental effects and make more meaningful comparisons among tests.
Changes in curve shape can reveal performance loss over time, such as reduced delivered capacity or an altered voltage decline under the same defined conditions. Engineers compare discharge results across battery states to identify these shifts. This analysis supports evaluation of degradation and helps determine whether a power source still meets the requirements of an application.
A useful test applies a defined load and records how voltage and delivered capacity change as the battery releases stored energy. Current demand, temperature, and the selected cutoff point should be identified because each can influence the result. Keeping these conditions consistent makes curves suitable for comparing cells, chemistries, or battery states.
Engineers relate the capacity delivered before cutoff to the power demanded by a device or system. The voltage profile indicates how the source behaves during that interval, while the load condition establishes how quickly stored energy is released. This combination supports operating-time estimates and helps determine whether a selected battery can sustain the intended use.
Discharge results help engineers compare cell chemistries and select power sources for electronic devices, transportation systems, and energy-storage applications. A suitable choice depends on more than nominal capacity: the battery must also maintain an acceptable voltage under the expected current demand and operating temperature. Curve analysis exposes these practical performance differences before integration.
