# How to Calculate Current Flowing through a Light Bulb

## Question:

You light a light bulb with a 1.5 volt battery. If the bulb has a resistance of 10 ohms, how much current is flowing?

## Answer:

0.15 amperes

Using **Ohm's Law,** the current flowing through the light bulb can be calculated by dividing the supplied voltage (1.5 volts) by the resistance of the bulb (10 ohms), which gives a current of 0.15 Ampere.

### Explanation:

To answer your question, we need to use Ohm's Law, which states that the current flowing through a circuit is equal to the voltage divided by the resistance. In this case, we have a voltage of 1.5 volts and a resistance of 10 ohms. To find the current, we divide the voltage by the resistance.

So, **I = V/R**

Plugging in the given values we get:

**I = 1.5V / 10Ω = 0.15A**

So, the current flowing through the light bulb is 0.15 Ampere.
