What is supply voltage in 45nm?

0.8-1.2V Depends on manufacturer and technology options.

In a 480 Volt 3-phase power supply what is the voltage between each lead?

  In 480 volt 3-phase power supplies, each single phase lead has a voltage of 277 volts from lead to ground. There are 277 * square root of 3 (1.73) = 480 volts phase to p

What voltages does a computer's power supply convert 120 volts of alternating current from a wall outlet into?

A personal computer's power supply receives 120 volts of AC and converts it to 3.3, 5, 12 volts of DC power. Another answer The secondary voltage could be any number of volt

What is dual voltage operation?

Dual voltage operation means the unit which has that feature can be operated with one of two voltages. This is a feature that may lend itself to marketing a PC in another coun

What is the nominal supply voltage?

The term, 'nominal', simply means 'named'. For example, the nominal supply voltage for a residence in the UK is 230 V. But this doesn't mean that the actual supply voltage is

You suspect that a power supply is faulty but you use a multimeter to measure its voltage output and find it to be acceptable Why is it still possible that the power supply may be faulty?

Yes, it can be faulty. Some damaged power supplies show good output voltages on the voltage range of a multimeter but, when you connect them, they don't work properly. One p

Dual power supply?

Dual power supply is used to describe a computer system with two  power supply units (PSU's). This is to provide extra power for the  computer's internal components.
