![]() Amps is not the total volume, it is the linear velocity of water through the hose. forget all that electron crap they teach. Electricity is no different than two cans with a string between them. The shape of the circuit determines the speed at which the motion will travel from point a to b. The current, or amps, is the speed of the motion through the wire. The voltage is the difference between the motion in point a and b. anon135269 December 17, 2010Įxcellent analogy! anon129554 November 24, 2010Įlectricity is simply a motion of a certain size. So which shock would be more, umm, shocking, #1 or #2? anon136138 December 21, 2010 That would mean, of course, since the watts are the same, that in Shock#2 there were more amps than in Shock#1. You're in the same place and everything else is the same, including the amount of watts that you were shocked with, except for one factor: in the Shock#1, there were more volts than in Shock#2. Here's a question that has puzzled me for a long time about volts and amps: Suppose you get two non-lethal electric shocks. W=6*4.5 equal to 27, can i operate a 13 watt energy saver? Please answer. If i have 6v battery and with 4.5ah which means anon157854 March 4, 2011Įxplained in very simple way. In physics the smaller the pipe the bigger the pressure which according to your analogy means that bigger resistance causes more bigger current, is that so? anon213616 September 12, 2011Ĭomplicated theory explained in simple terms. I do not know the number of Amps of suction power and I want to know if 900 watts is stronger than 12 volts or is it the same? anon248642 February 18, 2012Īnalogy to garden hose is bad. I am one of those guys gets the so called "hard stuff," but lack in the fundamentals of how to get there. I am a high school dropout, working on Piezoelectricity harvesting. So 10 amps corresponds to a 2200 watt (2.2 KW) device.īecause a home's main service is 240 volts, the math looks like this: 240 volts x 100 amps = 24,000 watts.So if I have a power supply, can I run 5 units that draw A quick response would be much appreciated. The current is mostly the power divided by the voltage = P/220 in amps. You cannot specify both current and voltage at the same time. With a better understanding of your RV's electrical system and some simple electrical formulas you can live comfortably on 30 amps with little to no problems. The key to living on 30 amps is to not exceed the amperage of an individual circuit, and to not exceed a total of 30 amps at any given time. ![]() A 50 amp plug has four prongs – two 120 volt hot wires, a neutral wire and a ground wire – that supply two separate 50 amp, 120 volt feeds.Ī 30-amp outlet supplies 3,600 watts (30 amps multiplied by 120 volts). Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts.Įquivalent Volts and Amps Measurements for Various Power Ratingsġ2 Volt, you have a 12 Volt power supply that delivers 1 Amp of current.Ī 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements. For example, if you have a power of 10W running at 5V, the current is 10W / 5V = 2A. The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): ![]() The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V): The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω): To calculate amps, divide the voltage by the resistance in ohms. Ohm’s Law provides an alternate formula to find volts if amps and the electrical resistance is known. You can calculate Current from Voltage either providing the Power, or Resistance values.
