What is the resistance of a lamp operating at 115 volts and using 0.25 amperes of current?
The resistance of a lamp operating at 115 volts and using 0.25 amp of current is 460. The relationship I used is Ohm's law.
Which has a least resistance 220 volts 100 watts or 115 volts 100 watts?
The higher voltage need more resistance, from the formula W = V2 / R. That means R = V2 / W. So 220 v 100 W is 484 ohms, while 115 v 100 W is 132¼ ohms.
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
What is the resistance of the heating element of an electric iron it the ampere draw is 8 amperes when 115 volts are applied?
Using Ohm's Law (E = I R) Voltage = Current x Resistance or switch around to get R = E / I: 115 volts / 8 Amperes = 14.375 Ohms The above is correct for DC current but is close enough to be used for AC current.
How many amps is 32 watts at 115 volts?
Divide the watts by the volts, so 32 / 115 is the answer in amps.
What does 115 vac mean?
115 volts alternating current
What is the wattage of 115 volts and 5 amps?
Ohms law will tell you watts equals volts times amps: 115 x 5 = 575
If a ceiling fan is 115 volts and 2.5 amps what be it be in watts?
You get watts from volts x amps, so 115 x2.5 = 287.5 watts
How to increase 115 volts to 220 volts?
You need a step-up transformer.
Can you use 240 volts to 220 volts?
Each voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages. The reason there is a range of voltages is to help the utility company out. They are mandated to keep the voltages within a + or - 5% range of a set voltage. Because there are loads coming on line and loads dropping off line the voltage fluctuates. Using a base voltage of 115 and 230 volts means that the voltage can rise by 115 +5% = 121 volts and drop by 115 - 5% = 109 volts. In the 230 volt range the voltage can rise by 230 + 5% = 241 and drop by 230 - 5% = 219 volts. As you see they are still in the usable voltage ranges.
Can you plug a 110V appliance into a 115V outlet?
120 Volts and 115 Volts refer to the same thing in the US. Residential electricity is provided at 120 Volts from the utility. High current devices such as motors are often rated at less than the supplied voltage (such as 115 Volts) because it is expected that there is a small amount of voltage drop in the circuit feeding them. The National Electric Code allows a 5% drop in voltage from the electric service so a 5 Volt drop from 120 Volts is OK.
Utility voltage is 115 volts at a frequency of 60 Hz what is the peak to peak?
A: Take 115 volts and multiply by 2.82. The frequency does not matter but he voltage does
