Series and parallel circuits

temperature, concentration, type of metal used, and type of circuit. The Data obtained by combining two metal solutions together connected with a salt bridge and measured with a voltmeter show that increasing temperature decreases voltage as well as increasing the Q value. Series circuits were found to increase the voltage of a cell as long as it was the same type of cell being used already within the cell combination. In the process, parallel circuits were found to not affect voltage and only affect current

Law & Series Circuits Introduction Theory: Ohm’s law defines the relationship between three important electrical properties namely: voltage, current and resistance. Mathematically, ohm’s law is expressed as: V=IR. By understanding the importance of conduction, one is able to determine the total resistance and visualize how resistors are connected in parallel circuits. In parallel connection, each resistor provides a separate path for current [I] so that the total resistance of a parallel circuit

different voltage and current values for series and parallel circuits under given circumstances. Theory: For 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

Ohm’s law & resistors in parallel & in series Lab 4 Class: PHY 1434-E475 Due date: March, 13 20144 Group Names: Hisham Sageer Objectives: Our object is to confirm Ohm’s law by analyzing the dependence of the electrical current as a function of voltage and as a function of resistance. Also, we studied the current flow and voltage in series and parallel. Finally, the lab determined the equivalence resistance of series and parallel combination of resistors and

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 into different circuits and for Ohm’s Law using only the current which passed through the branch). This

Physics Lab: RC Circuit Lab Emma Chen January 5, 2015 Team members: Alex Wang, Andy Val_ 1. Objectives The objective of this lab is to create an RC circuit that has a time constant of 10. 2. Method and Principle: The RC circuit that we created on the breadboard was a series circuit. RC circuits contain resistors and capacitors, and are connected to a voltage source. In our case, this voltage source was the battery. When we were measuring the voltage on the computer, we used a switch instead

voltage. Another similarity in the data was that as the amount of batteries increased, the voltage and current in the circuit also increased. This is because as more energy is added to the circuit, the amount of energy per charge increases (voltage), therefore increasing the amount of charge in one part of the circuit in one second (current). Two of the resistors used in the circuits were very similar both in data points as well as their corresponding resistance calculations. However, one of the resistors
