A lamp will only operate at its rated power at its rated voltage. So if you connected a 230-V lamp to a 110-V supply, its brightness would be very low. It does not matter whether the supply is AC or DC; a lamp would have the same brilliance at 230 V (AC) as at 230 V (DC).
As a rule of thumb for fixed-value resistances, a 10% drop in voltage results in a 19% drop in power.
What else can I help you with?
How much current flows through a toaster with a resistance of 20 ohms when it is connected to a 110 volt outlet?
Ohm's Law Volts = Current x Resistance Amps = V / R 110 / 20 = 5.5 Amps
What happens when you connect a 110 volt motor to 220 volts?
On a three wire supply system if you connect the two 110V wires together and they are across the phase they will short out and trip the breaker. If the two 110V wires are supplied from across the phase and connected to a motor then the motor will run. If the 110V wires are on the same phase nothing will happen.
What is voltage ratio on a transformer?
The voltage ratio of a potential, or voltage, transformer (PT or VT) depends upon the primary voltage to which it is connected. Accordingly, its voltage ratio varies considerably, as there is huge variety of system voltages throughout the world.Typically a VT's secondary voltage is standardised at 110 V which will match the full-scale deflection of a voltmeter connected to it (although it can also supply protective relays), while its primary voltage is then matched to the voltage of the system to which it is connected: in the UK, for example:11-kV:110 V33-kV:110 Vetc.
19 An electric heating element is connected to a 110 V circuit and a current of 3.2 A is flowing through the element How much energy is used up during a period of 5 hours by the element?
1,760Wh
What is the electrical voltage of a home service panel?
Either 110 v or 220 and 110, depending on how your house is wired.
A typical light bulb in your house is rated 60 W which means that the bulb dissipates 60 W when connected to a DC voltage of 110 V What is the currrent?
P=VI 60W = 110V x I I=0.54* A Hopefully in your house you are connected to 110 VAC and not DC. Same answer as above applies.
How much current flows in a 75-walt's light-bulb connected to a 110 voltage wall outlet?
The current flowing through the 75-watt light bulb connected to a 110-volt wall outlet can be calculated by using the formula: Power = Voltage x Current. Therefore, the current flowing through the light bulb would be approximately 0.68 amps.
Will the current in a light bulb connected to a 200-v source be greater or less than when the same bulb is connected to a 110-v circuit?
The current in the light bulb will be greater when connected to the 200-v source compared to the 110-v circuit, assuming the resistance of the light bulb remains constant. This is because current is directly proportional to voltage in an electrical circuit according to Ohm's Law (I = V/R), so a higher voltage will result in a greater current flow through the bulb.
When connected to a 110-volt power supply how much current does a light bulb draw when it has a resistance of 220-ohms?
The formulas you are looking for is I = E/R.
What will happen if 110 vac motor connected with 230 vac?
It will burn due excess current .
How deep do you bury 110 volt romex electrical line?
please tell your line voltage (like 230V,400KV,)!
What happen when 230 V load is connected to 110 V source?
The breaker will more than likely trip. If not then the appliance will not operate properly.
The voltage in the home is 110 volts. a light bulb has a resistance of 121 ohms. what is the amperage passing through the bulb?
I=v/r =110/121 =0.909A
A 75 watts110 volts bulb is connected in parallel with a 40 watts110 volts bulb. What is its net resistance?
We have two bulb in parallel debiting 75 + 40 = 115 watts under 110 volts. I -current amperes V -potential volts W -power watts R -resistance ohms knowing W = V*I V = I*R W = R*I2 Then: 115 watts = 110 volts * I => I = 115/110 = 1,045 amperes R = 115/(115/110)2 = 1102 / 115 = 105,217 ohms ------------------------------------------------------------------------------------------- Another way: First get the resistance of each bulb. Then we know that Rparallel = 1/(1/R1 + 1/R2 ) 75 watts = 110 volts * I => I = 75/110 ampere. R1 = 75/(75/110)2 = 1102/ 75 = 161,333 ohms. for the other bulb 40watts = 110 volts * I => I = 40/110 ampere. R2 = 40/(40/110)2 = 1102/ 40 = 302,5 ohms. meaning Rparallel = 1/(1/161,333+1/302,5) = 105,217 ohms That it's
Can you use a 130 volt 60 watt bulb in a socket that was made for a 110 volt 60 watt bulb?
yes the bulb will actually last longer
Why are some heating elements rated for 230 volts and some for 240 volts and what would happen if they are interchanged?
Probably because years ago the voltage supply in most residential applications was 110/220V. It was increased to 120/240V to increase efficiency. If you use a heater element rated at 230V in a 240V application you will be "overvolting" it and will probably reduce the life of the element. If using an element rated at 240V in a 230V application you will be "undervolting" it and it will probably not get quite as warm as it is designed to.
How do you run a 12 volt automobile light on 110 ac?
No. The bulb will burn out.
