A 9-volt battery is connected to a lightbulb as shown below. The lightbulb has a resistance of 50 ohms. What is the current (in A) that flows through the lightbulb?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.

![**Basic Circuit Diagram Explanation**
This diagram illustrates a simple electrical circuit consisting of a battery and a light bulb.
- **Battery**: The battery is depicted on the left side and is represented with positive (+) and negative (-) terminals. The voltage of the battery is denoted by the symbol \( V \).
- **Light Bulb**: On the right side, there is a light bulb indicating the output device being powered by the battery. The bulb is shown as lit, representing the flow of electric current.
- **Circuit Path**: A wire connects the positive terminal of the battery to the light bulb and then returns from the light bulb back to the negative terminal, forming a complete loop.
- **Current**: The flow of electric current through the circuit is depicted by an arrow labeled \( I \), indicating the direction of flow from the positive to the negative terminal of the battery.
In this circuit, the voltage (\( V \)) provided by the battery creates a potential difference, enabling the current (\( I \)) to flow through the circuit, thereby lighting up the bulb. This basic setup demonstrates a closed-loop circuit crucial for powering electrical devices.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7e432caa-dcb7-4410-861a-faaf21a0cda8%2F0eae11db-13ec-4614-a3bc-1bd638dcaf06%2Fzm1c6w_processed.png&w=3840&q=75)
