The formula for finding amperage is I = W/E. Amps = Watts/Volts. Without the value of the voltage to the bulb this question can not be answered.

How many amps will a 60 watt bulb draw from 120 volts?
Watts = Volts x Amps x Power Factor. An incandescent light bulb is a resistive load so PF = 1. ANSWER: = 1/2 Amp
How do you convert amps to amp hours?
volts times amps equals watts, a measure of power. Amps times hours equals amp-hours, a measure of electric charge. Electric charge times voltage is energy. So 120 volts at 10 amps for 4 hours would pass 40 amp-hours of charge, the power would be 1200 watts and the energy would be 4800 watt-hours or 4.8 kilowatt-hours. So volts times amp-hours equals energy in watt-hours.
How do you find kva?
k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA
How many 50 watt lights on a 15 amp circuit?
50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.
How many watts on a 40 amp circuit breaker?
about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)
How many amp hours does a 13 watt bulb use?
To calculate the amp hours used by a 13 watt bulb, divide the wattage by the voltage of the power source. For example, if the bulb is connected to a 120V power source, the current drawn would be 13W/120V = 0.1083 amps. This means the bulb would use 0.1083 amp hours for every hour it is on.
How many amps would a 150 watt bulb draw in a 120v circuit?
1 amp
How many 60 watt bulbs can a 15 amp handle?
A 15 amp circuit can handle approximately 8-10 60 watt bulbs. Each 60 watt bulb draws 0.5 amps of current, so you divide the circuit's amp rating (15 amps) by the current draw per bulb (0.5 amps) to get the approximate number of bulbs it can handle.
How many 25 amp bulbs fits 105 watt transformer?
Approximately 4 bulbs would fit a 105 watt transformer, as each 25-amp bulb consumes around 26.25 watts.
Can you use a 250 watt bulb with a 15 amp switch?
Yes, you can use a 250 watt bulb with a 15 amp switch. The switch is rated for up to 15 amps, which is more than enough to handle the power of a 250 watt bulb. Just make sure that the wiring and other components in the circuit can also handle the load.
What is the current of a 60 watt bulb connetcted to a 120 V power source?
.5 amp
What size circuit breaker is needed for a 300 watt bulb?
A 300 watt bulb requires a circuit breaker of at least 2.5 amps. This can be determined by dividing the power (300 watts) by the voltage (120 volts). However, considering normal breaker sizes, a 5 amp breaker would be sufficient for a 300 watt bulb.
How many amps does in a 60 watt bulb draw?
Without knowing the voltage, I can not tell you how many amps a 60 watt light uses. If you have a 12 volt system in a car, then a 60 watt light will pull 5 amps. If you have a 120 volt system in a house, then a 60 watt light will pull 1/2 amp. If you have a 240 volt system in an industrial building, then a 60 watt light will pull 1/4 amp.
How many watt in an amp?
That depends on the voltage.
How long will a 1 watt bulb operate on a 1 amp hour battery?
Please give the voltage and Ah rating of the battery and voltage rating of bulb.
What amp fuse do you use for a 100 watt bulb?
Fuses or breakers are used to protect the conductor to the load. A #14 wire conductor is rated for 15 amps. Most home circuitry is done with #14 wire. The minimum size breaker in an electrical panel is 15 amp so it looks like a 15 amp fuse or breaker can be used for a 100 watt light bulb.
How much current flow in 1 watt bulb?
Everything Depends on the voltage supply ...... Current flow (Amp) = Watt / Voltage the Current flow will be 1 amp if voltage is 1 V the Current flow will be 0.5 amp if voltage is 2 V the Current flow will be 0.25 amp if voltage is 4 V and so on.......
