What happens to voltage after a resistor?
What happens to voltage after a resistor? The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.” This is what we described in the Voltage Drop section above. Voltage drop = Current times Resistor size. Are resistors AC or DC? Resistors are “passive” devices, that is […]

What are the stages of combustion? Based on the experimental results the combustion in SI engines takes place in three stages as follows: Period of ignition Lag Or preparation phase. Flame propagation phase. after burning or flame termination phase. What is abnormal combustion? The Abnormal Combustion:- ➢ When the combustion gets deviated from the normal […]
Do capacitors need resistors?
Do capacitors need resistors? Capacitors do not always need a resistor, it depends upon the circuit. In the circuit shown, the capacitor will initially draw a lot of current if it is originally discharged. Drawing a lot of current from a battery or a power supply may not be a problem. How do resistors affect […]
