Question

6. (18 points total) All bulbs and all batteries are identical. a) (4 pts) Circ le the correct answer. The voltage measured across the battery in the circuit to the right is (less than) (the same as) (greater than) the voltage across the battery in the circuit to the left. b) (3 pts) Explain your answer to (a) ) (4 pts) Circle the correct answer. The current produced by the battery in the circuit to the right is (less than) (the same as) (greater than) the current produced by the battery in the circuit to the left. d) (3 pts) Explain your answer to (c). e) (4 pts) Circle the correct answer. For the circuit on the left, an amount of current In leaves the battery and flows into the bulb, and the bulb grows brightly. The amount of current loan that flows out of the bulb is (zero) (less than Iin but not zero) (the same as In (greater than

Explanation / Answer

6. given that all bulbs and batteries are identical

a. since all batteries are identical, and no internal resistance of the batteryis indicated

voltage across battery in A is identiocal to voltage across battery in B

b. as both batteroes are identical and no internal resistnace of battery is given the voltage across the terminals of the battery is independent oif the current in the circuit and hence remains constant

c. As circuit to the right has more resistacne it has less current

hence the current produced by the battery in the circuit to the right is less thanthe curent produced by battery in circuit to the left

d. As circuit to the right has more resistacne it has less current

qfor V = iR ( from ohms law)

for same voltage V

i = V/R ( inverse relation)
