What is parasitic resistance?
Parasitic resistance is resistance that you encounter in a circuit board or integrated circuit but not included in the original design -- an undesirable, unintended consequence of putting a concept into manufacturing. Since parasitic resistance does exist, you need to estimate its value and make sure the design still functions as intended. An example of parasitic resistance is the resistance of the traces in a circuit board or metal interconnects in an IC, the purpose of which is to connect components electrically according to the circuit diagram, but these connecting structures are not ideal. These connecting structures most likely also add parasitic capacitance and inductance to your design and, if substantial, should be included in your design (back-annotation) accordingly.
4 most important factors in an electric circuit?
electromotive force, current, resistance, and power
When checking resistance does the power have to be off?
Short answer: yes. Most modern multimeters will not be damaged by external power when measuring resistance. But they will give erroneous readings. It is best to remove the power and disconnect the measured resistance from the larger circuit. A multimeter determines resistance by applying a small voltage, and measuring the resulting current. If the resistor has an external voltage source, then it will interfere with the measurement. Furthermore, if the resistance is connected to a larger circuit, then the resistance of this larger circuit will also be involved.
Applications of rlc circuit?
An R-L circuit is one having both resistance and inductance. These are naturally-occurring quantities that most circuits possess and, so, don't necessarily have any practical applications per se. However, a practical example of an R-L circuit is an electric motor whose windings have both resistance and inductance.
What is principle of thermistor?
The thermistors are resistors whose resistance changes with the temperature. While for most of the metals the resistance increases with temperature, the thermistors respond negatively to the temperature and their resistance decreases with the increase in temperature. Since the resistance of thermistors is dependent on the temperature, they can be connected in the electrical circuit to measure the temperature of the body.
Can a short circuit cause low voltage?
Most likely a short circuit will cause no voltage. Due to the high current on a short circuit fault the over current protection of the circuit will trip. This will cut the voltage supply off completely.
Where is the most resistance lost in a series circuit?
Resistance isn't lost. The largest voltage drop will occur across the largest resistance in a series circuit.
What is the problem when you have 110-120 volt but when circuit is completed voltage drops to 30 volts?
A resistance in series with the circuit. It is most likely a wiring error, loose connection or load hooked in series instead of parallel.
The multiple paths in this circuit suggest that it is MOST LIKELY a?
parallel circuit.

In a series circuit where is the most voltage dropped?
At the point of highest resistance.
Why do some circuits need resistors?
A circuit does need resistance but not necessarily a resistor. without any resistance a circuit will be considered a "short circuit" and you power source will most likely overheat. Resistance can be created in millions of different ways. This could be something such as an or any other light source but also a module such as a capacitor resistor or diode. To get to you're question more directly a circuit needs resistance to keep from shorting out. A specific module(such as an LED) would need a resistor to lower the voltage so to a point where the module can accept the power without burning out.
Which resistor of a series circuit receives the larget voltage drop?
The resistor with the most resistance.
Which NSAID is most likely to cause ulcers?
Aspirin is the NSAID that is most likely to cause ulcers.
What is leakage resistance in RC circuit?
Leakage resistance in any circuit is resistance less than infinity where it is not expected, such as across an insulator. In the ideal sense, all circuits have leakage resistance because no insulator is perfect, but we usually ignore this except in special situations because it does not normally matter in real applications. In an RC circuit, leakage resistance would most typically be across the capacitor.
What two components in a timer circuit influence the timing most?
R (resistance) and C (capacitance).
