Question 29 NECO_MODEL_QUESTIONS_VOL1 • 2024 • PHYSICS • objective

A 12 V battery has an internal resistance of 0.5 Ω. It is connected to a circuit where a 4 Ω resistor and a 6 Ω resistor are in parallel, and this combination is in series with a 2 Ω resistor. (i) Find the current supplied by the battery. (ii) Determine the terminal voltage across the external circuit. (iii) Calculate the power dissipated in the 6 Ω resistor. (iv) If a second identical battery is connected in parallel with the first (same emf and internal resistance), what is the new terminal voltage across the external circuit?

Answer Options

A. I = 3.00 A; V_term = 12.00 V; P_6Ω = 7.20 W; V_term (two batteries) = 13.00 V
Correct Answer B. I = 2.45 A; V_term = 10.78 V; P_6Ω = 5.76 W; V_term (two batteries) = 11.35 V
C. I = 2.00 A; V_term = 9.00 V; P_6Ω = 4.50 W; V_term (two batteries) = 10.00 V
D. I = 2.45 A; V_term = 11.00 V; P_6Ω = 6.00 W; V_term (two batteries) = 12.00 V
Correct Answer
B
Correct Option:
I = 2.45 A; V_term = 10.78 V; P_6Ω = 5.76 W; V_term (two batteries) = 11.35 V
