Question:

Use the mesh current method to find the branch currents {eq}i_a, i_b {/eq} and {eq}i_c {/eq} in the circuit in the figure. And find currents {eq}i_a, i_b {/eq}, and {eq}i_c {/eq} if the polarity of the {eq}73 V {/eq} source is reversed. The values of {eq}v_1 {/eq} and {eq}v_2 {/eq} are {eq}73 V {/eq} and {eq}30 V {/eq}, respectively.

(a) Find the value of {eq}i_a {/eq}. Express your answer to three significant figures with the appropriate units.

(b) Find the value of {eq}i_b {/eq}. Express your answer to three significant figures with the appropriate units.

(c) Find the value of {eq}i_c {/eq}. Express your answer to three significant figures with the appropriate units.

(d) Find the value of {eq}i_a {/eq} if the polarity of the {eq}73 V {/eq} source is reversed. Express your answer to three significant figures with the appropriate units.

(e) Find the value of {eq}i_b {/eq} if the polarity of the {eq}73 V {/eq} source is reversed. Express your answer to three significant figures with the appropriate units.

(f) Find the value of {eq}i_c {/eq} if the polarity of the {eq}73 V {/eq} source is reversed. Express your answer to three significant figures with the appropriate units .
