Question 31 Four resistors of values 2 0, 4 0, 3 0, and 9 ? are connected across an 21-V DC source as shown in Figure 21-16. What is the voltage drop Not complete across the 4-Q resistor? Points out of 1.00 Flag question FIGURE 21-16 202 452 WWW 352 952 OV Answer: CheckQuestion 30 Four resistors of values 2 0, 4 0, 3 0, and 9 0 are connected across an 7-V DC source as shown in Figure 21-16. What is the current Not complete through the 9-Q resistor? Points out of 4SD Zero for video. 1.00 Flag question FIGURE 21-16 20 452 MAMA 352 952 I IV Answer:Question 29 Draw a circuit with a battery connected to four resistors, R1, R2, R3, and R4. Resistors R1 and R2 are connected in parallel, resistors R3 and Not complete R4 are connected in parallel, and both parallel pairs of resistors are connected in series. Which of the images below shows this . Points out of arrangement? 1.00 Flag question A) B) R12 R2 R12 ZR3 R4 R25 R4 C) D) R3 R4 R13 R2 R3 R4 R1 R2 O B OD O A O C30. Top part resistor - 212 42 Bottom part resistor - 312, an Battery voltage ( E ) = FV Equivalent resistance of bottom part Real = 3+9 = 121 current through a1 resistor - current is same in parallel and voltage is Same in parallel connection. so , I = E - 7 - Reg $12 I = 0 . 583 Amp
