WebTheory The purpose of this lab is to be able to demonstrate Kirchhoff’s first and second rules for electrical circuits. Kirchhoff’s Rules are used instead of Ohm’s Law when the Ohm’s laws start having limitations due to circuits being more complicated. Kirchhoff’s first rule states that the sum of all currents entering a junction must equal the sum of all currents leaving … WebThe reading of the ammeter for 500 Q is 9.82 mA. + 60 V. Required information Consider the given circuit where = 7 mA. An ammeter with internal resistance R¡ is inserted between A and B to measure lo. Determine the reading of the ammeter for the following values of Ri NOTE: This is a multi-part question.

WebExperiment No. 4 Voltmeter and Ammeter Objective: (a) To convert a galvanometer into a voltmeter reading up to V volts and calibrate it. (b) To convert a galvanometer into an ammeter reading up to I amperes and calibrate it. Apparatus: A galvanometer, a decade resistance box, a power supply, a multimeter, a piece of resistance wire and a cm scale. WebYes, the graph is linear. Perform a LINEST. Note: The slope should be 1 R. Note the slope and the uncertainty. Compare with the measured value (multimeter) of R. [R = 97.8 +0.12] Slope = 98.1411165222 Uncertainty = 1.633268962 Compared to the measured value (multimeter) of R [R = 97.8 +0.1 0], the measured value of the slope is 98.14111652 2.
WebNov 5, 2024 · Figure 20.4.5: When using a voltmeter, the circuit is modified. We can model this circuit quite easily by combining the voltmeter (modeled as a resistor) in parallel with one of the resistors: Reff = RVR RV + R = (10kΩ)(1kΩ) (10kΩ) + (1kΩ) = 10 11kΩ = 0.91kΩ The sum of the voltage drops across the effective resistor and the other resistor ...

WebDec 21, 2024 · The Ohm's law formula can be used to calculate the resistance as the quotient of the voltage and current. It can be written as: R = V/I. Where: R - resistance. V - voltage. I - Current. Resistance is expressed in ohms. Both the unit and the rule are named after Georg Ohm - the physicist and inventor of Ohm's law.
