Use the following information in the next Six questions: In the circuit shown, use the following: R_1 = 4 ohm, R_2 = 6 Ohm, R_3 = 3 Ohm, Delta V = 36 V. What is the total resistance of the circuit? 2 Ohm 4 Ohm 6 Ohm 13 Ohm What is the current through resistor R_1? 2.77 A 6A 8 A 9 A What is the potential difference between points B and C? 6 V 12 V 24 V 36 V What is the current through.R_3? 2 A 4 A 6 A 8 A What is the power dissipated by resistor R_1? 24 W 48 W 144 W 216 W How would the potential difference across resistor 2 change if points A and B were connected by a wire? It would increase. It would stay the same. It would decrease, but it would not be zero. It would be zero, answer:

Explanation / Answer

R1 =4 ohm , R2 = 6 ohm, R3 =3ohm, V =36 V

R2, R3 are in parllel

R23 = (6*3)/(6+3) = 2ohms

R1 and R23 are in series

R123 = 4+2 = 6 ohms

4) correct option is (c)

V =iR

i = 36/6 = 6A

5) correctoption is (B)

in series combination current is constant

i23 = 6 A

V23 = 6*2 = 12 V

6) correct option is (B)

V2 = 12V

i2 = 12/6 = 2 A

7) correct option is (A)

P1 = I1^2*R1 = 6*6*4 = 144 W

8) correct option is (C)

9) Correct option us (A)
