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.
Three bulbs of different watts are connected in series - which bulb will burn brightly - the higher wattage bulb or the lower?
lower wattage bulb
How many watts can be powered by a 9 volt generator?
There is no way to answer without knowing the wattage rating of the 9 volt generator. A generator's wattage rating depends on the size of the wire in it, the wattage of the rectifiers if it is a DC generator, and the horse power of the engine or motor that is available to turn the generator.
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.
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.
What is power rating of appliances?
Wattage = voltage x amperage. Every appliance in North America is built to work at 120 V, so you have the voltage. The amperage rating is probably written in the microwaves manual if the wattage is not. Remember the amperage you put on a circuit can't be more that 80% of what the wiring is rated for in the branch circuit.
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.
Can you mix bulb wattages in a 5 head floor lamp?
There is no electrical reason why this can not be done. Just remember that increasing wattage will add more draw to the circuit. If the circuit that the fixture is on has other loads, the circuit could be overloaded and may trip the breaker.
If a series circuit has a 12 v battery what is the current flow?
You'd need to know either the resistance or the wattage of the circuit. Ohm's Law: Current = Voltage divided by resistance or Current = Power divided by Voltage
