Find the equivalent resistance between the points A and B

Two hypothetical circuit element (shown by the blue rectangle), are shown in the figure. We will refer to them as the top circuit and the bottom circuit. Determine the best match to the behavior for each circuit

question is below

can someone help me with this problem and explain the concepts step by step

can someone help me with parts A-C and explain the concepts for the slope parts explain how exactly you are getting those numbers

Please answer only d

How do find the equivalent resistance of multiple resistors configures in parallel? You sum the resistances together and then divide by the number of resistors You average all of the individual resistor values. You calculate: 1/ (1/R1 + 1/R2 + + 1/Rn) ... You use the smallest resistor value.

How does the concept of duality apply to electrical circuits?

Consider the circuit in the given figure. Assume R1 = 120 S and R2 = 260 N. R R2 40 V Calculate current i in the given figure when the switch is in position 1. The current when the switch is in position 1 is mA.

Two coils are placed close to each other as shown in the figure. The coil on the left is connected to a battery and a switch, and the coil on the right is connected to a resistor.What is the direction of the current in the resistori. an instant after closing the switch?ii. after the switch has been closed for several seconds?iii. an instant after opening the switch?Choose your answers betweento. on the leftb. on the rightc. the current is zero.And clearly explain the reason for your answer.
