A moving coil ammeter gives a full scale deflection for a current i = 250 mA and its coil has a resistance RC = 0.75 Ω. It is  provided with a multiplier resistance Rm that allows a voltage measurement of up to 5 V. What is the value of the multiplier resistance? Select one: a. 0.5 Ω b. 2.0 Ω c. 20.75 Ω d. 19.25 Ω

The question can be found in the first image while the figure can be found on the other image. Thanks

A series R - L - C - circuit consists of a 25 ohms resistor , a 0.221 henry inductor, and a 66.3 microfarad capacitor , for what 60 - cycle impressed voltage will the current be 2.5 amps? 250V 125V 300V 110V

superposition Solve to find Ix' and Vx' (3V acting alone) and  use circuit simulation software( NI Multisim, or Multisim live, or Everycircuit)  to simulate and add properly ammeter and voltmeter to find Ix'' and Vx'' with 4A acting alone. Then solve for Ix and Vx from results. Then simulate the original given circuit (with 3v and 4A) to check the results (for Ix and Vx)

Design a voltage divider circuit (with a bleeder current of 20mA) that operates from a 500V source to supply the following loads: a) 400V @ 100mA b) 200V @ 50mA c) 100V @ 30mA

The following unbalanced Wheatstone bridge is constructed. Calculate the output voltage across points C and D and the value of resistor R4 required to balance the bridge circuit

Calculate the voltage output of a source when the source voltage equals 50V, the source internal resistance is 10 amphere and the load resistance is 50 amphere

Use the principle of superposition to find io and vo in the circuit in the figure shown.   Note:(the final answer is in the images as verification)

I am needing to find the Thevenin equivalent circuit as well as the voltage drops across a and b in the original circuit.
