please help me.
i typed two links by accident, it's only one link
can someone help me, the question is in these two links. there's no space between h and ttps.

can someone help me on these questions:
For the circuit in the picture above, answer the following questions:
a) Find out Thevenin’s equivalent resistance Rth for the load rheostat viewed from terminals a and b. (6 marks)
b) Determine Thevenin’s equivalent voltage Vth for the load rheostat viewed from terminals a and b by applying Superposition Theorem to two sources, VS and IS. Show your steps of all work with superposition. (12 marks)
c) Determine the resistance value of the rheostat to achieve the maximum power transfer to it, RL_max. Find out the maximum power PL_max. Calculate the voltage on and current through the rheostat at the maximum power, VL_max and IL_max, respectively, and indicate the voltage and current directions by sign in your calculation or by drawing of the circuit.

I am not certain what you need, it is straight forward.
a. Figure open circuit voltage Vab. That seems easy...you have V3+V2 equal to Vs Remember V3 has two currents thru it, 20ma + the current due to Vs. Vab= V3
Next, find short circuit current, you have Iab=I2-20mA
given that, you can deduce the Thevelin equivalent directly.
