(a) In Figure 1a, determine the unknown currents $i_1$, $i_2$, and $i_3$, given $i_a = 0.6A$, $i_b =$
0.8A, and $i_c$=1A.
(b) In Figure 1b, determine all the unknown voltages $V_1$, $V_2$, $V_3$, and $V_4$.
(c) Directly draw in Figure 1a the placement of the ammeter to measure $i_b$.
(d) Directly draw in Figure 1b the placement of the voltmeter to measure $V_3$.
