A9v battery is directly connected to each of 3 led bulbs. select the statement that accurately describes this circuit. a) a direct current is flowing through the bulbs using a series circuit so each bulb has the same current. b) a direct current is flowing through the bulbs using a parallel circuit so each bulb has the same voltage. c) an alternating current is flowing through the bulbs using a parallel circuit so each bulb has the same current. d) an alternating current is flowing through the bulbs using a series circuit so each bulb has the same voltage.

The correct option is (B).

Explanation:

The voltage is same in the parallel combination of the circuit but the current is different in this case.

The current is same in the series combination of the circuit but the voltage is different.

In the given problem, a 9 V battery is directly connected to each of 3 LED bulbs. The voltage is same in three LED connected to the battery. Battery supplies DC voltage. The direct current is flowing in the given circuit as the battery is connected to the LED.

Therefore,  a direct current is flowing through the bulbs using a parallel circuit so each bulb has the same voltage

the answer is b ) square root of 5

d. air pressure decreases as altitude increases.
