Volts Amps Resistance Triangle
Electronics is a major part of some aerospace technician s workday.
Volts amps resistance triangle. V 240 volts x i 10 amps p 2400 watts. So the current is lower in the tank with higher resistance. As an aerospace technician it is considered a basic skill to be able to calculate voltage current amps power watts and resistance ohms but remembering the formulas that go into those calculations can be difficult. Ohm s law calculator calculation calculate ohms power formulas mathematical ohm s law pie chart electric voltage drop electric current resistance formula watt s law emf magic triangle tip online voltage volts resistor resistance amps amperes audio engineering e v i r p v i calc conductivity resistivity relation relationship eberhard sengpiel sengpielaudio.
This formulae circle is very useful for many electrical engineering. This is known as ohm s law. R v i. Voltage current resistance triangle vir triangle may 20 2018 admin 0 comments.
The voltage v in volts v is equal to the power p in watts w divided by the current i in amps a. 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. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size.
Voltage current resistance or vir triangle is a visual representation of ohm s law formulas. The triangle illustrates the three formulas. Your fridge has stopped working on 12 volts and you want to check the 12 volt heating element is ok by measuring the resistance. First we need to work out the current.
The information for the element says it is 12 volts 170 watts so we need to calculate the resistance in order to check it. V v i a r ω. Because the resistance is greater and the voltage is the same this gives us a current value of 0 5 amps. For example we can calculate the power in watts by referencing the yellow area in the circle.
This is where a magic triangle can help. Now we can see that if we know two of the values for ohm s law we can solve for the third. If you want to do an electrical calculation involving voltage current resistance or power reference the formulae circle below. How to calculate with watts amps volts and ohms.
The power p in watts w is equal to the voltage v in volts v times the current i in amps a. There is a basic equation in electrical engineering that states how the three terms relate. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω.
