Question 3. (10 points) Four resistors are connected as shown in Figure 28.9a Find the equivalent resistance between a and c. R1-16 and R4-12 Ω R2-13 R3-4 (a) (b) What is the current in each resistor if a potential difference of 0.64 V is maintained between a and c. Calculate the current in each resistor I (for Ri resistor)- I (for R2 resistor)- I (for R3 resistor) I (for R4 resistor)- Which resistor uses more power, R or R4? Which resistor uses more power, Ri or R2? If R increases, the total current will If R, increases, the potential difference across Ri will increases, decreases or can't be determined. increases decreases or can't be If R, increases the potential difference across R2 wil determined increases, decreases or can't be If R4 decreases, the total current will increases, decreases or can't be determined Question 3.
