Watts, Amps, Volts.
The formula is simple:
P=VI
Power (in watts) equals volts times amps. For example a if a light bulb is powered by 110 volts and produces 60 watts you can determine that 60/110 or about .55 amps is going through the light bulb. 60=110 X 0.55 W = E x I, W = I2 x R, W = E2/R

What is the cost of using a 100 watts 220 volts lamp for twenty hours at three pesos per kilowatt hour?
6 pesos.
Independent and dependent are types of what?
Independent and dependent are types of variables. These variables are used mostly in science and math. When using independent variables you can control them dependent variables you cannot.
What is the formula for watts using mph?
The formula for calculating power in watts using miles per hour (mph) is: Power (watts) = 0.0098 * mph^3
3.516 kilowatts equals how many watts?
Move the decimal point three places to the right.
Ow do you calculate amperage with watts and volts?
You can calculate amperage (A) using the formula A = W / V, where W is the power in watts and V is the voltage. Simply divide the power in watts by the voltage to find the amperage.
How much can a 15W circuit breaker handle?
Answer for the US: Breakers are rated in amps, not watts. However, a 15A breaker can handle 15 amps, or about 1800 watts (using 120V), or 3600 watts (using 240V). However, this is only rated for noncontinuous loads (those not lasting for more than three hours). For continuous loads (loads lasting three hours or more), one must derate the circuit breaker by 80%. So for continuous loads, that same breaker should only have 1440 watts (using 120V), or 2880 watts (using 240V) on it.
How do you solve 3 dimensional equations?
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
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
What are the three variables that play an important role in a Practical Investigation?
Independent Variables, Dependent Variables and Extraneous Variables.
How can you represent values using variables?
You can represent values using variables. This can only be done with whole numbers.
In java all variables declared using a class are?
Reference variables
What type of linear programming can be found by graphical methods?
A linear programming question with two variables. Problems with three can be solved if there is a constraint that reduces them to effectively two variables. Linear programming with 3 variables, using 3-d graphs is possible but not recommended.
What are the three variables in a scientific experiment?
There are 2 variables and they are independent and dependant.
What is the cost of using a 100 watts 220 volts lamp for twenty hours at three pesos per kilowatt hour?
6 pesos.
When did light bulbs start using watts?
Light bulbs have always used watts.
How you can find greatest of three variables using c plus plus programming?
greatest = std::max (a, std::max(b, c));
