The circuit at right is made from an ideal battery connected to 4 ideal resistors as shown. i. What is the total resistance of this circuit? Show your work. R4= 352 R1 = 152 R3 = 452 ii. Find the current through each of the 4 resistors. Show your work. R2= 752 iii. Rank the potential difference across the 4 resistors from greatest to least. Explain your reasoning. iv. If resistor R3 is cut out of the circuit, without replacing it with anything, will the current through resistor R2 increase, decrease, or stay the same? Explain your answer or show your work.arrow_forward
- Help me solve it step by step, thank you in advancearrow_forwardConsider the circuit below (picture attached) How would you add a resistor with a resistance of 7.00 Ω to the circuit so that the current through the 3.0 Ω resistor is maximized? (This is already answered but I believe this correlates with part b. For this part the new resistor must be in parallel with the 4 ohm resistor) By how much does the current through 3.0 Ω resistor increase when you do what was descibed above? (Must be in units of ampheres please.)arrow_forwardplease do a step by step to undersatand also if u can provide the goal of the problem and the physic concept thank youarrow_forward
