Why cell combination needed? A cell is an electrical element which produces current and a battery is a set of some cells with series or parallel connection. A cell is an active element. To increase the rate of current and ...
Breadboard is a basic instrument for electrical and electronic engineering or telecommunication engineering or physics students or teacher or researcher. Teacher, students have facility to use lab equipment in college, university campus only. They can’t bring any equipment in house. ...
Important factors are before buying multimeter You have to consider some factors before buying a multimeter Budget Functions Safety feature Accuracy Design
Resistor and Resistance Resistance is a property of conductor. Resistivity depends upon conductor to conductor. Some have less resistivity which is good conductor, some have high resistivity which is bad conductor. In a circuit the wire we use is good ...
In 1826 famous German scientist Gorge Simon Ohm invented a relation between voltage and current. He expressed the relation in a formula which is known as Ohm’s Law. This formula seems very simple but it has a great contribution in ...
We know moving charge experiences a force due to magnetic field. Magnetic field creates force into conductor passing current through it. The charges of the conductor experience of force for magnetic field. Now we determine the force on a current ...
Wheatstone bridge is a bridge where four resistances are used. First and second resistance are connected in series; third and fourth resistance are also connected in series. Then the first and second two combinations are connected in parallel make Wheatstone ...
To understand completely Biot Savart Law some important rules or laws should be known are Maxwell cork screw Law, Fleming’s right hand rule. If current passes through a conductor it creates a magnetic field around it. The direction of the ...
