Resistor

The objective of the experiment was to measure the charging and discharging abilities of a resistor capacitor circuit. In a RC circuit the voltage is an asymptomatic function of the charging time. If a battery were connected in series in a circuit with a resistor, there would be a constant current. In contrast, if the battery were connected with a capacitor in series, the current would be time-varying, decaying to zero as the capacitor charges up. The results of the experiments verified the properties

both series and parallel circuits, resistors have an effect on the voltage and current going through the circuit without changing their own values. Equation 1 shows how the resistance value is related to the current and voltage in the circuit. V=iR Equation 1 V represents the voltage in the circuit, i represents the current in the circuit, and R represents the resistance value in the

Batteries, Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”, watch what happens, adjust some variables Why do electrons (blue dots) move? Draw a diagram of the battery, label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. Answer: The electrons

This one had red wires which transmitted current to two LEDs in parallel in order to light them up. Each LED had two 220Ω resistors through which the current exited the LED and green wires that led the current to ground. After calculating this circuit’s values, we used both the resistance equation and Ohm’s Law the same way we had for the first circuit (separating the two LEDs

Lab Report SIXTO LEONEL GUANO ROBAYO [ Group S-13] 05/12/2015 MEASURE THE POTENTIAL DIFFERENCE (V) AND CURRENT (A) VALUES BY USING A VARIETY OF RESISTORS, REMAINING CONSTANT EMF TO FIND OUT ITS INTERNAL RESISTANCE. Academic year: 2015-16 Title Measure the potential difference (V) and current (A) values by using a variety of resistors, remaining constant EMF to find out its internal resistance. Introduction “Batteries and cells have an internal resistance (r) which is measures in ohm’s

in the list above was NOT included in your pre-prac Investigation Design (or if there was anything you think could be improved) - include it now in your report below How does changing the resistor size affect the amplitude of signal voltage in a receiving circuit? Aim: To investigate how the resistor size in a receiving circuit affects

Link to Report Exemplar (see notes for extra information) Results Data Table Figure 1. Data table with the collected results showing resistor value vs signal strength. The signal strength (last column) was calculated using the following formula. V = counted squares (Second column) * (CRO volts per cm (Third column) * 10 ^-3) 10^-3 can also be written as E-3. E-3 is used since the results are being changed from millivolts to volts. An example of this is as follows. V = 0.2cm*(5mV * 10^-3) V

units of Joules/Coulomb and I is current with a units of Amps or coulomb/second. 2. From Part 3.1.1 (Power Supply): Produce a graph of output voltage Vout as a function of the sliding contact position x, measured from the bottom end of slide wire resistor. Verify that the data points fall on a straight line rather than a curve (don’t actually compute the slope). Did the current change while you varied the sliding contact position x? (hint your current meter was switched off during this part, but

Responsive Art Creating art has always been an interest to me. However sometimes I would like to see art become more than a still picture, painting, statue, etc. More recently the way in which a person can make still art come alive is even more interesting. When looking into a project to explore I went to Sciencebuddies.org and answered questions that reflected my interests. By answering these questions the website was able to recommend this subject to me. The more I learned about it the more
