Do the following problems: 1. www R₁ V₂ ww R3 R4 www R₂ + RL For the circuit shown above: a. Derive an expression for it in terms of V₁ and V₂. b. Find it if R₁ = 10 kQ, R₂ = 5 kQ, R3 = 6 kN, R4 = 3 kN, R₁ = 4 kN, V₁ = 5 V and V₂ = 3

Please answer question 2 with details on how to do it. Make writing legible. Thank you.

Shown in the figure below is an electrical circuit containing three resistors and two batteries. R3 10 R2 R1 Write down the Kirchhoff Junction equation and solve it for I, in terms of I, and Iz. Write the result here: Write down the Kirchhoff Loop equation for a loop that starts at the lower left corner and follows the perimeter of the circuit diagram clockwise. Write down the Kirchhoff Loop equation for a loop that starts at the lower left corner and touches the components R1, R2, and 4V. The resistors in the circuit have the following values: R, = 130 • R2 = 50 R3 = 10 Solve for all the following (some answers may be negative): | Amperes I = I, = Amperes Iz = Amperes NOTE: For the equations, put in resistances and currents SYMBOLICALLY using variables like RR2,R3 and I,,12,13. Use numerical values of 10 and 4 for the voltages.
