## Volts to Amps Conversion Formula

The formula for converting volts to amps is derived from **Ohm’s Law**:

I = V / R

Where:

Iis thecurrentin amperes (A)Vis thevoltagein volts (V)Ris theresistancein ohms (Ω)

Let’s say you have a **9V** battery connected to a **3Ω** resistor. To find the **current**:

`I = V / R`

I = 9V / 3Ω

I = **3A**

# How to Convert Volts to Amps

Identify the voltage(V) of yourpower sourceDetermine the resistance(R) of yourcircuitordeviceApply the formula: I = V / RCalculatethe result to get thecurrentin amperes

Imagine you’re designing a **circuit** for an **LED light**. You have a **5V** power supply and the LED has a **forward voltage** of **2V** with a **recommended current** of **20mA** (0.02A).

- Calculate the required
**resistor**: R = (V_supply – V_LED) / I_LED

R = (5V – 2V) / 0.02A

R =**150Ω** - Now, to verify the
**current**: I = V / R

I = 5V / 150Ω

I ≈**0.033A**or**33mA**

This calculation shows that a **150Ω** resistor will allow about **33mA** to flow through the LED, which is **safe** but slightly higher than the **recommended current**.

## How Many Amps in a 12 Volt Battery?

A **12V, 100Ah** car battery can provide:

1Afor100 hours

10Afor10 hours

100Afor1 hour(theoretically)

## Volts and Watts to Amps

To convert volts and watts to amps, we use the **power equation**:

**P = V × I**

Where:

Pispowerin watts (W)Visvoltagein volts (V)Iiscurrentin amperes (A)

Rearranging this equation, we get:

**I = P / V**

A **60W** light bulb connected to a **120V** power source:

I = P / V

I = 60W / 120V

I =0.5A
