When resistors are connected in series then what happens to the watt?
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
How many 125 watt bulbs can be used on a 15amp circuit?
Assuming that your voltage is 120 volts the maximum wattage on that circuit is W = A x V = 15 x 120 = 1800 watts. Code only allows circuits to be loaded up to 80% capacity. 1800 x .8 = 1440. 1440/25 = 57 lamps. Assuming that your voltage is 240 volts the maximum wattage on that circuit is W = A x V = 15 x 240 = 3600 watts. If the question is from a 240 volt country you will have to find out what the local electrical regulations are for circuit loading.
How much Ampere when volt 415?
That would depend on the power output (watts) of the circuit. Volts times the Amperage equals the Wattage of the circuit. You do not have enough information in your question. Volts is the force applied to move the electrons in the circuit, and amps are a measure of the quantity of electrons moved through the circuit over time. Thus a circuit of 415 volts and 1 ampere will deliver 415 watt-hours of power. Yet a circuit of 1 volt at 415 amps will deliver the same 415 watt-hours of power, but with less force.
Is 800w load?
An 800W load refers to an electrical device or system that consumes 800 watts of power during operation. This measurement indicates the rate at which energy is used, and it can be important for determining the appropriate power supply or circuit capacity. For example, if multiple devices are connected to the same circuit, their combined wattage should not exceed the circuit's rating to avoid overload.
How is the total lighting load in amperes determind?
The total lighting load in amperes is determined by first calculating the total wattage of all lighting fixtures in a circuit. This total wattage is then divided by the voltage of the circuit (usually 120V or 240V) using the formula: Amperes = Watts / Volts. Additionally, factors like the power factor (for non-resistive loads) may be considered to ensure accurate calculations. It's also important to account for any local codes or regulations that might affect the overall load calculation.
What is the wattage used in circuit 19volts 3.25amps?
61.75
How many watts does a light timer use?
The wattage rating of a timer is governed by the manufactures specification. As long as the light bulbs wattage rating is not higher than the timers rating, the timer will be alright to use in the circuit. The circuits load is what governs the wattage of the circuit.
Why does an electrical breaker trip when you use a lot of appliances in the house?
since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
Will changing circuit breakers in box for electric heat reduce heating bills?
No, all it will do is make the circuit unsafe if a larger breaker is installed or make the circuit trip unnecessarily if a smaller breaker is installed. You pay for the wattage that you use. Less wattage used, less cost on your utility bill.
How many electric griddles can you plug into a circuit?
It depends on the wattage of the electric griddles and the capacity of the circuit. As a general guideline, a typical residential circuit can support 2-3 electric griddles of around 1500 watts each, but it's always best to check the circuit's capacity and the griddles' wattage to ensure safe usage.
What is the max number of luminaries that can be installed on a 20-amp 277-volt branch circuit?
The maximum number of luminaries that can be installed on a 20-amp, 277-volt branch circuit depends on the wattage of the individual luminaries. To calculate this, first determine the total wattage capacity of the circuit, which is 20 amps multiplied by 277 volts, equaling 5540 watts. Then, divide this total wattage by the wattage of each luminary to find the maximum number of units that can be installed without exceeding the circuit's capacity. It's also essential to consider the NEC guidelines, typically allowing for a maximum of 80% of the circuit's capacity for continuous loads, which would further reduce the number of luminaries.
What is the symbol used in a formula to represent the rate of energy dissipation in an electric circuit?
"W" for watts, or wattage
How many 75 watt bulbs can be on a 20 amp circuit?
Common sense with electrical systems dictates that current in a circuit be limited to 80% of nameplate (20A). The number of 150W lamps will be limited to 12 in this scenario. This answer can be superseded by local ordinance.
What is a object that uses up the energy being delivered in an electrical circuit called?
The object that uses up the energy being delivered in an electrical circuit is called what?the wattage
Would a multimeter connected in series as part of the circuit measure current or power consumption or voltage or wattage?
Current.
How many floodlights can you connect on a 10a circuit breaker on a 220 voltage supply?
To answer this question the wattage of the flood lights must be stated.
What is the maximum number of 100-W bulbs you can connwct in parallel in a 120-V home circuit without tripping the 20-A breaker?
You can connect a maximum of 24 100-W bulbs in parallel on a 120-V home circuit without tripping the 20-A breaker. This is calculated by dividing the total circuit wattage (2400 W) by the wattage of each bulb (100 W) to find the number of bulbs that can be safely connected.
