What is a Thermistor? A thermistor is defined as a type of resistor whose electrical resistance varies with temperature changes. Although the resistance of all resistors will slightly fluctuate …
What is a rheostat? A rheostat is a variable resistor that is used for current control. They can vary the resistance without interruption in a circuit. The construction is …
Georg Simon Ohm has found the nature of electrically conductive materials to oppose the flow of electrical current through them and it is named as resistor. To indicate the …
Ohm’s Law- The relationship between Voltage, Current and Resistance was first discovered by the German physicist Georg Ohm in any DC electrical circuit. Georg Ohm observed the electrical current …
On these factors the resistance of earthing system are depends- Shape and material of electrode or electrodes used. Depth in the soil at which the electrodes are buried. Specific …
Measurement of resistance- Properties of resistance plays an important role in determining performance specification for various circuit elements including coil, winding, insulation etc. Apart from this resistor are use …
