Using nodal analysis for the circuit, write the nodal equation at V1 and at V2

For the circuit below, fill in the values for the mesh equations. Between the vaiables there will be a space for a + or - sign but the first entry or the voltage value will have to be entered with a negative sign if necessary, just enter the number if it's positive. Just enter the values for the mesh equations. Notice that there is a space for the + or - sign between 1 & 12 and 12 & 13. 22k2 4.7k2 10k2 1.0kQ 47k2 25V 15V kO*12 kOʻ13 = kO*11 kO"12 kO*13 = kO 12 kOʻ13 =

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.
