Depends on the wattage of the bulb. Formula is Power (watts) = Voltage * Current (A).

Therefore for a 55w bulb, in a 12V car, bulb draws 4.6Amps.

Why do we use thicker wires for heaters than for lamps?

Heaters draw a lot more amperage. As your amperage increases, so does resistance to the flow of the current. Too much resistance, and your wire overheats, melts the casing, and can potentially catch fire.


Can using larger wire sizes reduce amp draw?

Using larger wire sizes will not reduce amp draw. The amp draw is determined by the electrical device or load connected to the circuit, not the wire size. Larger wire sizes are used to reduce voltage drop and heat generation in the wiring, but they do not directly affect the amp draw of the circuit.


You were given aload 2500 watts how much it draw amps?

To calculate the amperage draw, you need to know the voltage of the circuit where the 2500 watts appliance will be used. You can use the formula: Amps = Watts / Volts. For example, if it is a 120V circuit, the amperage draw would be 2500 watts / 120 volts = 20.83 amps.


What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?

To calculate the amperage draw, you can use the formula P = V x I, where P is the power in watts, V is the voltage in volts, and I is the current in amps. Given that the power is 1200 watts and voltage is 120 volts, you can rearrange the formula to solve for current. Therefore, I = P / V, so the amperage draw of the heater would be 10 amps.


How many amps will a 3 phase 480 volt 4kw heater draw?

To calculate the amperage drawn by the heater, you can use the formula: Amperage (A) = Power (W) / (Voltage (V) * Square root of 3). In this case, the amperage drawn will be approximately 5.8 Amps.

How many watts does a compact fluorescent bulb draw?

Look for an amperage on the ballast. Multiply this amperage by the connected line voltage. This will give you the wattage of the unit.


Can you run a motor of greater amperage draw with a motor of less amperage draw?

It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.
