Q1. (a) The circuit of Figure 1 has V₁ = 4V and R = 3k. Calculate the current / shown and the power generated by the source. (b) The circuit of Figure 2 has /₁ = 3mA, /2 = 5mA and R = 3kQ. Calculate the voltage V shown and demonstrate that the power generated by the sources is balanced by the power dissipated in the resistors. (c) The circuit of Figure 3 has /1 = 3mA, V₁ = 4V and R = 3k.
