How do you solve for current using volts and watts in a problem?
Amperes measure the rate of flow of electricity in a conductor Volts measure electrical pressure Watts measure the amount of energy or work that can be done by Amperes and Volts Relationship: Work = Pressure x Flow or Watts = Volts x Amperes When you know two variables you can calculate the other Formulas - This formula referred to as the West Virginia Formula (W - VA)Watts = Volts x Amps Volts = Watts / Amps Amps - Watts / Volts Refer to link below for more information
How many volts are 5000 watts?
Volts * Amps = Watts so since we don't know the voltage in the above equation: 1 volt * 50,000 Amps = 50,000 Watts OR 50,000 Volts * 1 Amp = 50,000 Watts Or 1,000 Volts * 50 Amps = 50,000 Watts Or The combinations are effectively infinite.
How many milliamps in 48.8 watts?
Milli amps is a measure of current whilst watt is a measure of power. The missing element is voltage as the formula is:- Power = Voltage * Amps ie power in Watts is the product of Volts (in Volts) times Amps (in Amps)
How much current must flow to carry 240 watts at 120 volts?
240 watts at 120 volts requires 2 amperes. Power = voltage * current
How do I figure watts if I know voltage and ohms?
Volts time amps equals watts so watts divided by volts equal amps.

How are amps different from watts and volts?
Amps measure the current flowing in a circuit, watts measure power output, and volts measure voltage difference. In an electrical system, volts x amps = watts, so they are related but measure different aspects of electricity. Volts represent the force pushing electrical current, while amps indicate the rate of flow, and watts show the total power consumed or produced.
How do you covert watts to amps?
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
How many watt in amp?
Watts cannot be directly converted to amps because the two units measure different quantities. Watts are a measure of power, while amps are a measure of electrical current. The relationship between watts, amps, and voltage is given by the formula: Watts = Amps x Volts.
How can you calculate current when you have volts power?
You can calculate current by dividing the power in watts by the voltage in volts. The formula is: Current (in amperes) = Power (in watts) / Voltage (in volts).
What is the procedure to convert kilowattas to kilovolts?
You cannot convert watts to volts. Volt is a measure of potential difference.. in other words the 'push' in the circuit that makes the current flow. Watts are a measure of energy used. V x I = W Where V= Volts I= Current in Amps (A) W= Watts
What is the Formula to measure current if power is given?
Power = Voltage x Current Watts = volts x Amps
25 amps is how many kw?
Amps is a measurement of current. Watts (or kilowatts) is a measure of power. To get the power from the current, you have to know the electrical potential or volts used to produce the current. Amps × Volts = Watts (or Current × Electrical Potential = Power). Incidentally, a kilowatt is 1000 watts, so you'll have to divide your answer by 1000. e.g. if your volts is 40, then 25 amps × 40 volts = 1000 watts. 1000 watts (divided by 1000) is 1kw or kilowatt.
How many watts are in 30 volts?
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.
How do electricians measure electricity?
Volts, amperes, watts and ohms. pressure (or force), current, energy, and resistance.
115volts are how many watts?
That's like asking: How much time does it take to go 15 MPH? It depends on at least one other factor. In your case, you cannot know watts unless you know voltage and current or resistance (from which you could derive current, because E = I x R). Once you know the current drop across the 15 volts, you can multiply I x E and get P, i.e., amps times volts equals watts.
How much current does 60 watts Operated at 480 volts have?
To calculate the current, we can use the formula Power (watts) = Voltage (volts) * Current (amps). Plugging in the values given, we get 60 watts = 480 volts * Current. Solving for Current, we find Current = 60 watts / 480 volts = 0.125 amps.
