- Use the color code to find the resistor values in Figure 8-23 and solve all missing values. FIGURE 8-23 Determine resistor values using the color code and find all missing electrical values.arrow_forwardIf the voltage source in the figure attached is set to 35V, apply Kirchhoff's Voltage Law to the circuit to show that the algebraic sum of voltages in the closed path is equal to zero. Please state all assumptions Please show all steps in your calculationsarrow_forwardA 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 Ωarrow_forward
- Please explain why setting up KCL above is incorrect for this circuit. It was my understanding that you can choose the direction of current. Use nodal analysis.arrow_forwardKirchhoff's current law (KCL) states that: Select one: a. the sum of all currents at any node in a circuit equals zero b. the sum of all currents leaving a node equals to the sum of all currents entering the node c. All of the given answers.arrow_forwardhi, this is about thevenin circuit. (Note: The Lightbulbs have the same resistance. V2 and R3 currently shown are incorrect. ), thanks.arrow_forward
