everything is explained well but i have a small inquiry, first why did we disregard r4 and didnt include it, and the second is can you show step by step how u reached that final formula applying millman's theorm? like can u explain where and how u got each value? and why for I1 and R3 u didnt transform it to a voltage source? can u please extensively explain these points? thank you

For the circuit shown, for T4.3, when does point where the current source is removed cannot be considered an open circuit. My professor says that there will still be current flowing into the point of removal as the reason.
However for T4.1,, why does the point at r3 can be considerend an open circuit since no current in flowing into r3?

Preface: For this problem we are assuming the voltages are constant (also known as "de" voltages). This isn't actually the case, but, we will later learn that you can treat alternating voltages (such as would actually exist in this scenario) by appropriately scaled constant voltages. Hair dryers have a small motor that runs a fan, plus two heating coils for making the air hot enough to dry hair. The circuit diagram below depicts a hair dryer on the right side (everything to the right of the nodes labeled HOT and NEUTRAL) and it is receiving power by being plugged into a wall socket that provides 120 V (as depicted to the left). One of the heating coils can be switched in or out of operation via the switch S1 shown in the circuit. The resistor R1 ensure that the motor is not damaged by excessive voltage. Note that the model of the motor is a voltage “source” in series with a resistor, but this source will only consume power.
