The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts. For more information see the Related Link shown below.
74LS08 is a quad two-input AND gate with LS-TTL logic levels.
When you say holdhold supply of 230volts, you are referring to the RMS value, not the peak value.
The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the logic… circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
A hand held test meter is usually rated for 1000 volts.
Be more specific it depends on the ratio of the windings.
A:The best platinum thermocouple can give upto 64mv
A: The question is not specifically qualified. normally for a dry human it is around 28v for begging to feel it. break the skin or get wet that is another question
The secondary voltage (output voltage) of a transformer depends on the turns ratio of the transformer, and is limited by the practical insulation levels of the secondary win…ding, so can be very high indeed. Power transformers used in electricity transmission systems have secondary voltages in the range of hundreds of kilovolts.
The 74LS series is designed for a 5 v supply so they should be used with the right supply voltage. 6 v would probably not destroy them but the logic functions might be impaire…d.
What is the maximum voltage drop normally permitted from the supply authority to the consumer's terminal?
3 % (+ or -) on LT side is generally permissible. (in India)
The voltage across the resistor is whatever voltage is applied. The only maximum here would be a voltage that would damage the resistor. If you think this might happen, you'll… have to look up such a voltage from the data sheets.
