If this were a real circuit, what would be the sources of experimental error? (Remember experimental error does not refer to mistakes made by you) This is a question from a physics 2 lab about resistors in series and parallel
Below four simple RC circuits are shown. In each case, the capacitor starts with zero charge at t = 0 and 'charges up' through the resistor. Match each of the RC circuits (labeled i, ii, iii, iv) to each of the plots (labeled A, B, C, D).
SOLVE FOR FIGURE B (Open Circuit) and PLEASE EXPLAIN HOW YOU GET IT. Note: There is a voltmeter so there is no current in open circuit. Directions: Complete the table by providing the values for Vab, Vac, Vbd, and Vcd. Refer to Figure 3b. Note that an ideal voltmeter has infinite resistance while an ideal ammeter has zero resistance. You may need to compute for the current in the circuit to find the unknown voltages.

Charging a Capacitor: An RC circuit includes a basic switch. In position "a", the battery, resistor and capacitor are connected in series, and the capacitor charges. In position "b", the battery is replaced with a short, and the capacitor will discharge. Two voltmeters and an ammeter have been added to the circuit. A) The switch is moved to position "a", and the capacitor begins charging. At any given instant in the process, let "I" represent the current flowing through the ammeter, and let "q" represent the charge that has accumulated on the positively charged capacitor plate. Enter an expression for Kirchhoff's Loop Rule where the sum of the voltage changes totals zero. B)Since the current is the rate of charge flow, substitute "dq/dt" for "I" in your expression from the previous step. With a little algebra, rearrange your expression so that all references to time appear on the left-hand side and all references to charge appear on the right-hand side. Input an expression for the…
