Ohms, amps, watts to volts conversion. amps (A) - Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts. In other words the lower the voltage, the less current potentially flows through the victim. Watts can be converted to volts using current and a Watt’s Law formula, which states that current is equal to power divided by voltage. Watts and amps are somewhat confusing because both are flow-rates, yet we rarely talk about the "stuff" which does the flowing. amazing, never been able to get this stuff in my Head and you've managed it so succinctly mate, thanks ever so much, Cheers. Amps = 56/20 = 0.257 Amps (A) Calculating volts to amps with ohms If you select this option as your type of calculation, you need to enter the correct values of the volts and ohms in their required fields. If we break the circuit, with a switch for example, then no current will flow. thanks for the free lesson. So, to calculate watts, the following formula is used. This is what makes electricity do things. The SI unit of voltage is a volt, the unit of amperage is an ampere (usually shortened to amp), and the unit of power is a watt. But you can definitely get an approximate. Below are some example equations that are solved using the formulae. Start by selecting the type of current which can either be the direct current (DC) or Alternating current (AC) single phase/ three phase. For example, a current of 2A flowing through a bulb with a voltage of 12V across it generates 24W of power. The power P in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V): P(W) = PF × I(A) × V(V) AC three phase amps to watts calculation Calculation with line to line voltage Firstly, the voltage in the UK is officially 230v (single phase, domestic). I have a question.. Can the magnetic energy be converted to electric enegergy somehow by properly placing them on a flywheel? here is a smart formula i'd like to pass on to beginners like myself. I understood completely and I understood that it is not on the money, and those of us who don't have to act like know it all's realize that there are factors involved that makes the math close, but there is room for error. Everything is stepped down from 230 to 120. Derived from the formula V x A = W, a watt is the rate of power flow that results from amps flowing through a volt’s electromotive force. I agree with your 'approximately' as obviously cable and other elements in the circuit will further lower the current. And how come they only sell guides but not the finished product. Watts would be the power (volts x amps) the water could provide (think back to the old days when water was used to power mills). Then why in England on ALL commercial work sites the max voltage used is 120? Amps is like the flow rate (say litres/sec). In this formula, P is power, measured in watts, I is the current, measured in amperes, and V is the potential difference (or voltage drop) across the component, measured in volts. Rik Ravado (author) from England on November 04, 2009: LiamBean from Los Angeles, Calilfornia on October 23, 2009: Lovely. But in order for the current to flow, the electrical conductor or wire must loop back to the battery. Why is your power bill in kilowatt-hours and your battery bank in milliamp-hours? In the United States, the standard voltage output for a household outlet is 120V. Thanks for the heads-up Rik. Knowing that 120 volts multiplied by the unknown current is equal to 1,000 watts, we can divide 1,000 watts by 120 volts to find that the amount of current is about 8.3 amps. Rik Ravado (author) from England on February 06, 2010: Thanks for your comments - I still maintain 120v is safer than 230v. Then let's take a much deeper look. Before i cant do the difference between volts and watts. So one of the most frequent misconceptions or at least misunderstandings we hear from our customers is how amps, volts and watts relate to each other in a solar system (or any system for that matter) and why more amps is not necessarily more power. Volts is like the pressure in a pipe (say the “head” in metres). You have a 12 Volt power supply that delivers 1 Amp of current. Everyones a cridic. For example: if you have a power of 12W running at 2V, then the current is 12W / 2V = 6A. Rik is an engineer who has held a range of marketing, technical support, and management roles.
