What is the current in an circuit with 120-volts and a 60-watt light bulb?
Use the formula P= VI (power = potential x current) where (watts = volts x amps). The current I in amperes is equal to the watts divided by the volts, 40/120. The bulb is using 1/3 amp of current.
How many amps is 280 watts at 24 volts?
In a Direct Current circuit power is equal to the product of current times voltage or in another form of the same equation, power divided by voltage equals current in amps. 280 watts divided by 24 volts equals 11.6666666 amps.
What is the difference between volts and current?
Electrical current is the number of elementary charge units (coulombs) that pass by a given point in one second. Current, measured in amperes, is coulombs per second. Electrical voltage is the "pressure" behind that current. Voltage, measured in volts, is joules per coulomb.
How many volts are equal to one watt?
The voltage delivering 1 watt depends on how many amps are present. We use watts to measure power (P), and amps (I) times volts (E) equals watts. We sometimes see the equation P = I x E written to express this relationship. Let's look at a couple of instances. If we have 1 amp times 1 volt, we'll get 1 watt. But 1/2 amp times 2 volts also equals 1 watt. Likewise, 10 amps times 0.1 volts equals 1 watt. Or 0.001 amps times 1,000 volts (1 milliamp times 1 kilovolt) equals 1 watt. As you can see, it is a combination of voltage and current that gives us wattage (power), and any voltage you can imagine can be used to get one watt of power when you have the correct current (amperage).
How many amps are in 1900 watts at 110 volts?
Depends on the supply voltage. For UK 230 Volts, 1800 Watts would mean the current drawn was 7.83 Amps.Watts=Volts x Amps, so Watts divided by Volts gives the current in amps.
How many watts are equal to volts?
There are zero volts in a watt. Watts are the product of amps x volts. As you can see there is not enough data given to answer the question. If you use this equation, Watts = Amps x Volts , you should be able to get the answer you are looking for.
What is the amperage in an electric circuit when the voltage 120 volts and the resistance is 40 ohms?
Ohm's Law states Voltage = Current x Resistance. You rewrite the equation as Current = Volts / Resistance to solve for current.
What is the equation of resistance?
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
What the equation of resistance?
Ohm's Law: Resistance in ohms is voltage in volts divided by current in amperes.
What does l represent in electrical?
It usually represents current in amps as in the equation V=IR (volts equals current times resistance)
What is the resistance of an electric frying pan that draws 12 amperes of current when connected to a 120 volt circuit?
Given R=? I=12 ampere V=120 Volts equation I=V divided R Solution; R=12 ampere 120 Volts answer (10)
What is the current in an circuit with 120-volts and a 60-watt light bulb?

What is the ratio of potential difference to the current of a circuit?
The name given by engineers to the ratio of "electrical potential difference" (expressed in volts) to "rate of current flow" (expressed in amperes) is "resistance" (expressed in ohms).
What is the Formula to measure current if power is given?
Power = Voltage x Current Watts = volts x Amps
How many volts would does it take to operate a DVD player with 550 ohms resistance and a current of 0.2 amps?
In the U.S. 120 volts. <<>> Using the equation E = I x R, Volts = Amps x Resistance = 110 volts.
The mathematical relationship between current voltage and resistance is known as?
Ohm's LawAnswerIt's not known as anything; it's simply an equation. Ohm's Law describes constant proportionality between current and voltage for certain, but not all, materials (linear or ohmic) -it has nothing to do with this equation.
What is the resistivity equation?
Ohms law. R = E/I,where R= resistance in ohms, E = voltage in volts, and I = current in amperes.
