## What is the current in a 60 watt bulb connected to a 120 volt source?

Question: Problem 3 A 60-W (60 Watts) light bulb connected to a 120-V (120 Volts) source draws a current of Answer: **0.5 A (0.5 Amps)**.

## How many amperes flow in a 60 watt bulb that is rated for 120 volts when it is connected to a 120 volt circuit?

Physics 4-26

Question | Answer |
---|---|

A battery does 18J of work on 10 coulombs of charge. What voltage does the battery supply? | 1.8 V |

What is the current in a 60W bulb connected to a 120V source? | 0.5 Amps |

What is the power dissipated by a toaster that has a resistance of 40 ohms and is plugged into a 120 V outlet? | 360 Watts |

## How many amps does 60 watts draw?

The Wattage is divided by-110. A 40 Watts bulb is capable of drawing 0.36 Amps to operate. A 60 watt bulb draws **half a Amps** to operate.

## How many 60 watt bulbs can be on a circuit?

Assuming a 60 watt light, you can put up to **24 lights** on a 15 amp breaker. If you are using low-wattage LED bulbs, an LED bulb using 10 watts, you can install up to 150 bulbs on a single circuit.

## How do you calculate the current in a light bulb?

We are given the voltage and the power output of a simple circuit containing a lightbulb, so we can use the **equation P=IV** to find the current I that flows through the lightbulb. 19.51P=IVI=PV=60 W120 V=0.50 A. Thus, a half ampere flows through the lightbulb when 120 V is applied across it.

## How much current flows through a 60 W light bulb that is connected to a 120 V electrical line?

How many amperes flow through a 60-W bulb connected in a 120 V circuit? Ans. Power= current x voltage. Rearranging terms we find that current = power/voltage = 60W/120V = **0.5 Amps**.

## How do I calculate current?

The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as **I = V/R**. The SI unit of current is Ampere (Amp).

## How do you calculate amps from watts?

Obtain Amps from Watts and Volts:

Insert the number of Watts (W) and Volts (V) below and click on Calculate to obtain Amps (A). The formula is **(W)/(V) =(A)**. For example, if you have a power of 10W running at 5V, the current is 10W / 5V = 2A. This comes from the equation I = P / V.

## How many amps does a 100 watt bulb use at 120 volts?

For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw **0.833 Amps**.

## Which light bulb draws the most current?

(a & b) **bulb C** is the brightest and draws the most current. Since it is connected across the terminals of the battery, bulb C “sees” the full voltage of the battery, but bulbs A and B “see” only half of the battery voltage.
