The amount of current in a circuit depends on the amount of voltage available to motivate the electrons, and also the amount of resistance in the circuit to oppose electron flow just like voltage, resistance is a quantity relative between two points (cramblet, boorn, crowell, and starck) there are two types of circuits namely, series and parallel. Rc circuits physics 226 lab the equation that determines the exponential graph in figure 3 is as follows v c is the voltage across the capacitor (in volts, v.

Physics lab report how does the length of a string holding a pendulum affect its oscillation method 1 method 1 you will need the following apparatus: a pendulum, a piece of string, a clamp, a clamp stand and a timer. Phys 102 formal simple dc circuits lab report 1 kaitlyn greiner formal lab report: title of experiment: simple dc circuits date performed: july 16th, 2014 lab partners: erin phlegar and stephen few physics 102l, section: 02 professor teklu abstract: in this lab, my objective was to understand the relationships between resistance, potential difference, and current in a simple circuit. An introduction to dc circuits printer friendly version: in parallel circuits, this equivalent resistance is always smaller than any of the original resistors in a parallel circuit, each additional branch increases the size of the main line current that must be drawn from the battery lab: resource lesson: worksheet: physicslab. To compare current values at the three resistor locations of a series circuit and to compare voltage drops across the three resistors of a series circuit and the voltage gain across the battery a complete lab write-up includes a title, a purpose, a data section, and a conclusion/discussion of results.
Physics 1 lab: series and parallel circuits introduction: ohm’s law is the most fundamental relationship between the quantities of electric potential (voltage), electric current, and resistance it is valid for many circuits and allows us to calculate one quantity if we know the value of the other two ohm’s. Physics 1 lab: series and parallel circuits 4 while the bulbs are still lit, carefully disconnect one of the bulbs from the circuit observe what happens to the other bulb and the ammeter reading and record your observations part two: parallel circuit if a battery is being used, remove two cells from the battery.
The calculated equivalent resistances for the series circuits will abide by the equation r eq = r 1 + r 2 and for the parallel circuits the value will be similar to 1/r eq = 1/r 1 + 1/r 2 the current flow is expected to be uniform throughout the series circuits, but will be stronger through the smaller resistor in the parallel circuits. Physics lab report of circuits knowing how the variables are used in calculations and electrical currents is important in determining the value of the resistor and how it affects the current in the circuit. Rc circuits physics 226 lab m) using the two values from l) , calculate the half-life of the circuit n) find the percent error of your measured value to the calculated value.
To compare voltage drops across the three resistors of a parallel circuit and to compare current values at the three resistor locations and outside of the branches of a parallel circuit a complete lab write-up includes a title, a purpose, a data section, and a conclusion/discussion of results. • the report begins with a short statement of what is being measured, and why •the procedure and results are then briefly described for each major part of the exercise do not reproduce the lab manual, but do specify any parameters you chose and any differences from the suggested procedures.
