Rules of Electrical Circuit | Parallel and Series
Basic Rules that Electrical Circuits always follow.
Here we will Understand Rules of Electrical Circuit in Parallel and Series. Basic rules that electrical circuits always follow.
Basic Rules of Electrical Circuit
- A voltage of 1V across a resistance of 1 Ohm will cause a current flow of 1 Amp, and the resistor will dissipate 1 Watt (all as heat).
- The current entering any passive circuit equals the current leaving it, regardless of the component configuration.
- The danger of electricity is current flowing through your body, not what is available from the source. A million volts at 1 microamp will make you jump, but 50V at 50mA can stop you dead.
- An electric current flowing in a circuit does not cause vibrations at the physical level, unless the circuit is a vibrator, loudspeaker, motor or some other electro-mechanical device.
- External vibrations do not affect the operation of 99.9% of electronic circuits, unless of a significant magnitude to cause physical damage, or the equipment is designed to detect such vibrations (for example, a microphone).
- Power is measured in Watts, and PMPO does not exist except in the minds of advertising writers.
- Large capacitors are not intrinsically “slower” than small ones (of the same type). Large values take longer to charge and discharge, but will pass AC just as well as small ones. They are better for low frequencies.
- Electricity can still kill you!
Parallel Circuit Rules
- Electronic Components in a parallel circuit share the same voltage.
- Total resistance in a parallel circuit is less than any of the individual resistances.
- Total current in a parallel circuit is equal to the sum of the individual branch currents.
Series Circuit Rules
- Electronic Components in a series circuit share the same current.
- Total resistance in a series circuit is equal to the sum of the individual resistances. Thus total resistance in a series is greater than any of the individual resistances.
- Total voltage in a series circuit is equal to the sum of the individual voltage drops.
