V Ir Triangle

This may at first seem to present a problem since 800 ohms is not a standard value available in the e12 range.

V ir triangle. Put the numbers into the equation and calculate the answer. Here v 10 ma 22 kω 220 v. Circuit diagram here is a diagram showing i v and r in a circuit. Just enter 2 known values and the calculator will solve for the others.

Introducing the constant of proportionality the resistance one arrives at the usual mathematical equation that describes this relationship. Use the ohm s triangle to find the value of connected voltage source. From the left triangle we obtain v ir which states that voltage is directly proportional to resistance and current. Simple to use ohm s law calculator.

See the examples below. 3v is applied across a 6 resistor what is the current. Calculate power current voltage or resistance. V 3v i r 6.

Where i is the current through the conductor in units of amperes v is the voltage measured across the conductor in. So value of connected source is 220 v. To help remember the formula it is possible to use a triangle with one side horizontal and the peak at the top like a pyramid.

Ohm s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Select the equation you need use the vir triangle. I v r. Let s use the second ohm s law triangle in another example.

Any one of these can be calculated using ohm s law if you know the values of the other two. Using the ohms law triangle the required resistance is calculated from the formula r v i which gives us 12 0 015 800 ohms see below for vf. In the top corner of the ohms law triangle is the letter v in the left hand corner the letter i and in the right hand bottom corner r. Use ohms law to relate resistance current and voltage.

Voltage current resistance or vir triangle is a visual representation of ohm s law formulas. Don t forget current is measured in amps. This is sometimes known as the ohm s law triangle. It should be very easy now.
