At this platform of calculator-online, you can find out en efficient tool known as ohms law calculator. Yes, this ohm calculator concerning the ohm’s law equation that was derived by the Georg Simon Ohm in 1827.
Well, before knowing more about our ohms law calculator, let’s we tell you about what is ohm’s law.
In 1827, the mathematical law of electric current was derived by the Bavarian physicist Georg Simon Ohm. It is the most fundamental law that defines the relationship between the current (I), resistance (R), voltage (V), and power (P). More specifically, ohm’s law defined that the current (I) through a conductor between two points is directly proportional to the voltage (V), and is inversely proportional to the resistance (R).
The Bavarian physicist Georg Simon Ohm derived a formula in which the resistor’ current (I) in amps (A) = (is equal) to the resistor’s voltage (V) in volts divided by the resistance R in ohms (Ω):
Ohm’s law formula is stated as:
Current (I) = (Voltage,(V))/(Resistance,(R)) in Amperes, (A)
How to find current becomes easy with our simple ohms law calculator concerning formula for current.
The team of a calculator-online provided a simple and efficient tool known as “ohms law calculator” through which you can readily find out the value of voltage (V), current (I), power (P), and resistance (R) concerning simple ohm’s law formula.
However, two of these values should have to be known to figure out the remaining two values.
Hence, remember that you will get the results concerning the standard units that you selected!
There is no need to stick on certain mathematical calculations to determine the value of voltage (V), current (I), power (P), and resistance (R). Our ohms calculator does all for you within a couple of seconds. Our ohms law calculator is not only convenient to use, but it also works efficiently! Let’s take a look!
As mentioned above, you will get your outcomes concerning the SI units that you select before calculating!
Ohms law derived that the amount of current (I) through a metal conductor in a circuit is directly proportional to the voltage (V) impressed across it, for respective temperature. Georg Simon Ohm expressed his discovery in the form of a simple ohm’s law equation that describes how voltage, current, and resistance interrelate:
V = IR
In this ohms law equation – voltage (V) is equal to the current (I) multiplied by resistance (R). Well, using this ohm’s law equation manipulate into two variations, solving for current (I) and resistance (R), respectively:
I = E/R and R = E/I
Our ohms law calculator also works as a current calculator as it concerns a simple current formula. When a voltage (V) and resistance are given, then you ought to use a formula for current. You can calculate current using the given formula!
[Current (I) = Voltage (V) ÷ Resistance (R) ] I (amps) = V (volts) ÷ R (Ω)
Find the current flowing through a 3 Ω resistor when a potential difference of 30 V is applied across it.
Solution: Current (I) = V ÷ R; I = 30 V ÷ 3 Ω; I = 10 A
An ohm law calculator is also referred to as a resistance calculator as it helps you to calculate resistance. When a voltage (V) and current (I) are given, you can find out resistance using a simple formula for resistant.
[Resistance (R) = Voltage (V) ÷ Current (I) ] R (Ω) = V (volts) ÷ I (amps)
Find the value of unknown resistor which drops 5 V when 20 mA current is flowing through it.
Solution: Resistance (R) = Voltage (V) ÷ Current (I) amps; R = 5 V ÷ 20 mA; R = 250 Ω
The above ohm’s law calculator is reliable to do so! When current and resistance are known, you can easily find out the voltage using a simple voltage formula:
[Voltage (V) = Current (I) x Resistance (R)] V (volts) = I (amps) x R (Ω)
Find the voltage applied across 15 kΩ resistors when 10 mA current flows through it.
Solution: Voltage (volts) = Current (amps) x Resistance (Ω); V = 10 mA x 15 kΩ; V = 150 V
The above calculator will help you to calculate the power using a simple power formula. If voltage and current are given, then you can easily calculate the value of the power.
Power (P) = Voltage (V) * Current (I)
If the application of 15 Voltage potential drop across a resistor results in 10 mA current flowing through it, then how to evaluate the power dissipated across it.
Solution: P = V * I; P = 15 V * 10 mA; P = 0.15 W
Well, know it’s time to know about Limitations of ohms law.
Our ohms law calculator is a straightforward tool that utilizes simple ohm’s law formula to find out Voltage (V), Resistance (R). Current (I), and Power (P).
