R₁ R₂ 4.7kQ 6.8kQ C www VS1 Ra 5V 10.0kQ V$2 10V B Figure 1: D 1. Prove: (a) Kirchhoff's voltage law is valid for the circuit in Figure 1. Do this by substituting the measured algebraic sums from Table 2 into a loop equation written around the outside loop of the circuit. (b) Kirchhoff's current law is valid for the circuit of Figure 1 by writing an equation showing the currents entering a junction are equal to the currents leaving the junction. Use the signed currents computed in step 10.
