You measure the current flowing as 6 amperes. But the value of voltage is unknown and you cannot measure it because of some reason no available voltmeter to use.
Always sketch a rough diagram of the circuit you are considering, before you start making calculations based on the values in the circuit which are already known to you.
You can finalize these ideas or concepts as follows: Cheers to all and Good night! If you know the values of current and resistance in the circuit.
When you did this, you will obtain: In a more technical expression, you can state it as: The relationship of voltage, current, and resistance was studied by German Physicist, George Simon Ohm.
This is one of the fundamental laws of Physics.
You want to know the resistance of the resistor; but you have no ammeter. Current flow in the circuit increases as the voltage is increased, and decreases as the resistance is increased.
This rule is very useful especially when we already dealing with the more complex circuits. With Constant EMF lower resistance passes large current. Write letter E in the small triangle, which has been formed above the line, and the letters I and R below the line, it will look like as what as shown below.
This is simple as: Obviously, the title of the law was derived itself on his name.
Draw the magic triangle, put your thumb you want to calculate, which in this case the E- and you are left with the formula you need. The voltage and the resistance of a circuit are known to you; but in this case the ammeter you need to measure the current is lost or broken.
This is how you will solve it. Given a constant voltage emf applied to the circuit, current flow decreases as the resistance of the circuit increases.
Take you have a circuit in which you have to measure the resistance to be ohms, and the current to be milliamperes mA. Supposed you have an unknown resistor connected across the battery, and you find by measurement that the voltage across it is 24 volts.
You know the values of current and voltage, but in this case you have no ohmmeter to measure the resistance. The concept is just simple: Put your thumb over the symbol I.
Sketch out the magic triangle illustration given below. You can therefore rewrite the mathematical given above in another way like what as shown below: The rule for working the magic triangle to give the correct formula is as follows: Substitute the known values for E and I, and your answer is R.
This is what you called the magic triangle!Understanding Basic Electrical Theory.
Ohms Law. The most fundamental law in electricity is Ohm’s law or V=IR. The V is for voltage, which means the potential difference between two charges.
This voltage drop principle leads to another important law in basic electrical engineering, Kirchoff’s Voltage Law (KVL). This law states that. Some of the basics of electrical engineering are current, voltage and resistance.
These are three of the essential building blocks of electricity, and it is important to understand electricity at a fundamental level before learning complex terms. Electrical current, measured in amperes, is the free.
In this course, complex topics are made simple with step-by-step lessons that cover some of the most important, basic concepts in electrical engineering.
