Question

A 9.0 V battery is connected to a bulb with a resistance of 3.0 Ω. What is the current flowing through the circuit?

a) 3.0 A
b) 6.0 A
c) 9.0 A
d) 12.0 A

Answer 1

The correct option is a. Using Ohm's law, the current flowing through the circuit with a 9.0 V battery and a 3.0 Ω bulb is found to be 3.0 A, which is answer choice (a).

Step-by-step explanation:

To find the current flowing through the circuit, we use Ohm's law, which states that current (I) is equal to the voltage (V) divided by the resistance (R). In mathematical terms, this is I = V / R. Given a 9.0 V battery and a bulb with a resistance of 3.0 Ω, we calculate the current by dividing the voltage by the resistance:

I = 9.0 V / 3.0 Ω = 3.0 ATherefore, the current flowing through the circuit is 3.0 A. This corresponds to answer choice (a).
