Find the Thevenin and Norton equivalent circuits for the circuit shown in figure below. Take care that you orient the polarity of the voltage source and the direction of the current source correctly relative to terminals a and b.
$R_1 = 10\Omega$, $R_2 = 25\Omega$, $R_3 = 15\Omega$, $v_1 = 15V$, $i_1 = 1A$
Your answers will be validated to +/- 0.01 absolute.
First, use node voltage equation to solve for the open-circuit voltage:
$v_{ab} = \text{____} V$
Then, by zeroing the sources, we can computer the equivalent resistance
$R_t = \text{____} \Omega$
Finally, compute the equivalent current source for Norton equivalent circuits.
$I_n = \text{____} A$
