You have a new Digital Multimeter and would like to know its input impedance. You have three different pairs of resistors with values of 600, 60k and 6M. You construct a voltage divider from each pair, power it with 20V DC and use the new meter to measure the output voltage. For R=600, you measure 10V. For R=60k, you measure 9.95V. For R=6M, you measure 6.66V. What is the input impedance of your new meter?

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...

I am working on my Physics lab report where it was all about Direct Current Measurement and Ohm’s Law. We had 5 different resistors and had to construct different circuits using a power supply, volt-ohm-milliammeter (VOM) and a digital multimeter to get measurements of resistance, voltage, and current. Nominal values of resistance and tolerance Resistor Nominal Resistance (Ohms) Tolerance (Ohms) R1 680 +/- 68 R2 1000 +/- 50 R3 1500 +/- 75 R4 4700 +/- 470 R5 10,000 +/- 500...

You are using a half-bridge circuit to measure the strain on a beam. Both strain gages have nominal resistances of 120 Ω and strain gage factors of 1.92. The other two resistors used in the circuit have nominal resistances of 120 Ω An adjustable power supply is used to apply a 5.00 V source voltage to the bridge circuit. Prior to loading the beam, the bridge is initially balanced. a. If the beam experiences an axial strain of...

You have an antenna with an input impedance of Z (140 -j35)2 at f 120 MHz. You would like to match this load to a 70Ω transmission line using a single stub tuner (vp-2.2x108 m/s). Using the Smith chart, determine the distance d away from the load and the length l of a short-circuited parallel stub to accomplish the matching goal at the design frequency. Estimate the reduction in radiated power if the operating frequency is changed to f 125...
