Can you use a 12v 60hz 210 va power cord to replace a 120v 60hz 150w cord?
No, it has to do with the insulation rating of the individual cords. 12 volts can be used on a voltage rating of 120 volts. But 120 volts can not be used on a 12 volt rated cord. As a point of interest most power cords have an insulation rating of 300 volts.
How many volts of electricity did the first TV use?
A TV will use all the volts you give it. The amount of power on the other hand varies greatly depending on type and vintage.
Is sj cord rated for 300 volts to be used for 480 volt?
No. The voltage rating needs to be 600 volts for 480 volt power.
How you transfer your tv from 120 volts to 240 volts?
The TV might have a panel on the back where you can adjust the voltage that it works on. If not, you need a step-down transformer to convert 240 v to 120 v for the television, and it must be rated at the amount of power the TV takes, which could be 100-200 watts.
How many volts does it take to power an audio speaker?
A 50 watt, 8 ohm speaker requires 20 volts to drive it to full power. Watts equals volts and amps, while volts equals amps times ohms.However, the 8 ohm rating is actually a minimum rating, and depends on frequency. Also, driving a speaker to full power on a continuous basis is not good for the speaker. (Or for the ears, either.)
Can 230 Volts rating TV operated on 150 Volts?
It would probably not work on 150 volts. Many televisions can be adjusted to work on 230 v (Europe) or 120 v (USA).

What is function of power grid system?
power grid is an interconnected system of electrical cable and electrical equipments to transmit electrical power from plant to load centers!
How do you measure power rating?
Power is measured in Watts. It is Volts times Amps (as figured in the simplest way).

What does the volt rating mean on cordless drills?
The volts on cordless drills are based on the battery power. The volt rating reflects the battery that is in the drill.
Can you use 12v 500mA adapter to tv antenna that has 12v 200mA?
YES!If you have a TV antenna amplifier rated at 12 Volts and 200 milliamps, you can use any power supply that will deliver at least 200 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. note: 200 milliamps is 0.2 amps. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 200ma that it needs.
Do televisions use single-phase or 3-phase power?
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
