Some electrical machines work on the principle of
electromagnetic induction. For such events to occur, we need inductor due to which reactive power flows in the circuit. Since, this power is due to the energy storing elements in the circuit like inductor and capacitor. That is why, we need reactive power in a electric circuit.

What role does switch play in an electric circuit?
a switch is used to isolate the a flow of current through a circuit , by breaking its connection, there is often a switch at the beginning of a circuit which would isolate the supply - voltage , from the load or " circuit " , in terms of higher - rated voltage circuits ( mains power) ; the switch performs a safety function where it provides a quick , safe and effective means of swathing off the circuit , providing a safety function - purpose , allowing the user to quickly remove power in the event of an emergency , for the switch to carry out its duty, it needs to have an air gap across its contacts contained within , rated so that at the designed/ rated voltage it maintains safety isolation / not allowing an electric arc / spark to jump across the gap .
What is power factor significance in calculating the AC power?
Power Factor is one of most significant parameter in calculating AC Power. As we know it is cosine of angle between AC Voltage and Current it comes in picture while calculating power in AC circuits Power In AC (P) = Voltage (V) X Current (V) X Power Factor Let us take an example of Power with Power factor and without power factor for same circuit. Let Us assume V = 125 Volts I = 1 Amp Power Factor = 1 Then P = 125X1X1= 125 Watts But for any circuit when Power factor is below 1, to execute same power, Circuit has to draw more current. for example P = 125X 1.25 X 0.8 = 125 Watts In first example power factor of the circuit was unity = 1 and in that condition current of the circuit was 1 amp whereas in second example power factor of the circuit is 0.8 due to which current of the circuit increases to 1.25 amp to execute the same power. Now due to increase in current of the circuit many factors are affected like heat loss, Conductor's specification , Class of insulation etc. Thus it can be concluded after going through above explanation that power factor play a significant role in AC power calculation as well as in actual practices.
What are the Recommendations of a crisis management When do you utilize reactive crisis management What role does PR play in reactive crisis management?
3.2GHz processor
What the role of a resistor in an led circuit?
a resister is to RESIST current flow....if the LED gets the full effect of the power supply, the LED will immediately blow out.
What is the role of the fuse?
To protect the rest of the circuit.
The role of the circuit breaker is what?
to prevent a circuit from overloading if too much current flow safely interrupt the circuit if it becomes overloaded
What is the role of a breaker in a circuit?
the breaker makes sure that nothing in the circuit is damaged by an increased amount of amperage or voltage
What is the role of the battery in a circuit?
"A battery stores electrical energy."
What is role rheostat?
it is a device which is used to change the resistance of circuit.
