Set up 3 equations with 3 unknowns (the currents) for the Basic Network: (1) the Kirchhoff Current Equation for junction g, and (2) the two Kirchhoff Voltage Equations for the two loops a-k-j-g-c-a and i-g-c-f-i. Write these equation in terms of ??s, I?s and R?s ? NO NUMBERS UNTIL THE END.

Some Help

This will be an algebra problem once you have 3 equations and 3 unknowns (the three currents I1 I2 I3). You will solve for the 3 unknowns Read the description of the loops carefully. Go around the loop counter . For example, the Kirchhoff Voltage Equation for Loop a-k-j-g-c-a is:

-I1R1 ? I1R4 ? I3R3 + ?1 = 0

4) Solve these equations by Algebra and show clearly the steps in your calculation.

NOTE: Solve your equations algebraically without inserting values for the resistances and emf's. For example, display the formula for I1, in the following form:

I1 = Terms with E s and R s only Terms with R s only A Anmeter R R4 [b] R4 K = J E = 3.13V E2=1.60V R = 752 h=82& Lab Report R3=24& 682 Ei C d R3 f 3R2B g+ I = 16.8 mA, I2 = 10.3mA [3=269 Kirchhoff s, voltage Law magnitude (volts) voltage Sign between (or-) points bi - k-j jc c-a + 1+++ Sum 1.273 1.159 0.672 3.10
