what do the measuring instruments that can measure electricity, measure? And what not?
They measure voltage and resistance and not length and width
Technology is rapidly changing and one of the most important branches of technology is electronics that involves components such as?
Resistors, capacitors, inductors, semi-conductors
Among all the components in the field of electronics, what is the most commonly used component?
Resistor
Among all the components in the field of electronics, what is the most commonly used component?
Resistor
it is a discrete component that counters the flow of current in an opposing manner. It makes the output of one circuit applicable to the input of another circuiit.
resistor
two classifications of resistor
material composition and construction
Are examples of resistors that can be classified in accordance to their material composition.
Carbon composition and wire- wound resistors
Are examples of resistors that can be classified in accordance to their material composition.
Carbon composition and wire- wound resistors
are examples of resistors classified according to their construction
fixed resistor and variable resistor
