The current I in amps is equal to the apparent power S in volt-amps (VA), divided by the RMS voltage V in volts (V): I(A) = S(VA) / V(V) So amps are equal to volt-amps divided by volts. amps = VA / volts or A = VA / V Example Question: What is the current in amp...
Amp to Watt conversion: Learn how to calculate watts from volts and amps in both DC and AC circuits. Understand the impact of power factor & reactance on the calculation.
To find the amperage of a current based on the number of millivolts, you will need to know the number of watts produced by the current. Once you know the number of millivolts and watts, you can use the basic power conversion formula "Watts = Volts x Amps" to find the number of a...
Ohm's law is an important mathematical formula that electricians and physicists use to determine certain measurements in a given circuit. The formula is: V=I×RV=I×R where V is the voltage, measured in volts, I is the amount of current measured in amps or amperage and R is the resistan...
Figure 3. V: The cylinders are arranged in two banks set at an angle to one another. HowStuffWorks Figure 4. Flat: The cylinders are arranged in two banks on opposite sides of the engine. HowStuffWorks Let's look at some key engine parts in more detail. ...
Converting VA to Volts How to convert VA to volts? Use the following formula: V=(Va*Pf)/A Where V stands for RMS volts, A stands for the RMS amps, VA stands for volt-amps, and PF stands for the power factor. What is KVA?
a. Provide the equation when the loop rule is applied to the loop abcdefgha, in terms of the variables in the figure. b. If the current through the top branch is I_2 = 0.51 A, what is the current through the bottom, I_3, in amps? (Diagram) What does the figure represent? a...
Determine the power lost to the thermal energy of the wire, and express your answer as a percent. How many kilograms are there in an imperial ton? In the electrical circuit in the figure, determine the power dissipated in the 3.1 k Ohm resistor. A) 13.884 mW B) 53.067 mW C) 24.25 ...
Capacity:Capacity refers to the amount of charge a battery holds. It is measured in milliamp-hours (mAh), or amp-hours (aH). A battery’s mAh is normally listed on the side of the battery, and you can figure out how long you can expect the battery to last using this simple equation...
Figure out the voltage for your country. Different parts of the world have different standards for voltage; in North America, electricity is 120 V, but in most other countries it is 220 to 240 V. Step 3 Multiply amps by volts to find Watts. Divide this number by 1000 to find kilowatts...
