What is the difference between power limited and power non-limited electrical circuits?
In wiring or cabling, high voltage lines and low voltage lines should be separately installed. High voltage lines which carry AC 120V/208V/277V/480V should be installed in one conduit, and low voltage lines which carry DC 12V/24V/48V and non-current carrying lines should be installed in another separated conduit. It is one of the strict requirement of NEC. When AC 120V wires and DC 12V wires are laid inside of one rack, they should have spaces more than 6 inches between them. - dona
What is use of step up transformer?
A step-up transformer increases (or "steps up") the voltage of an alternating electrical current. For example, a step-up transformer could be used to increase 120V AC to 277V AC to provide power to 277V electrical equipment in a building that does not already have a 277V electrical system.Other examples where a step-up transformer might be used include these:Using 240V AC equipment with a 120V AC mains supply.Generating high voltage for use with tubes, such as a CRT.Generating high voltage for use in electric energy distribution.
What is the voltage difference between the two holes in a wall socket?
One of the holes is a power wire and the other is a ground. Without both you have no voltage. As soon as the power wire is grounded either through the other side of the circuit or by some careless human you have 110 volts.
How much current does a 120v 1200w hair dryer draw?
10a
How do you work out amps from watts and voltage?
Ohm's law states that you could calculate the current (Amp), resistance (Ohm), or voltage (Volt) as long as you know the other two. Watts is not part of this law. Therefore, your question does not give enough information.
A microwave oven uses 1000 W of power The voltage source is 120V What is the current flowing through the microwave?
I = P/V = 1,000/120 = 81/3 Amp.
How much current flows in a 12 watt radio connected to 120 volt circuit?
A 120V household electrical outlet supplies 12 watts of powerwhen the current is 0.1 Ampere (and the power factor is 100%).
What is voltage across a 75 ohm resistor with 1.6 A current?
120v
How much power will a 230v adapter pull from a 120v outlet?
Power is multiplication of voltage and current. You need to know the load current drawing to establish the power. It is a bad idea to use 230 v adapter in 120 volts outlet
An electric heating element has a resistance of 16ohm and is connected to a voltage of 120v How much current will flow in the circuit?
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
What voltage does the power supply uses in US?
Input would be 120v at 60hz. Standard US wall power.
What is the power when a voltage of 120V drives a 2-A current through a device?
Power is volts time amps, so 120 V time 2 A = 240 W. That is, of course, assuming that the voltage is DC, or the load is purely resistive. If there is any capacitive or inductive reactance in the device, and the voltage is AC, the true power will not be equal to the apparent power because of a phenomenon called power factor due to phase angle of voltage not being equal to current.
Why would a high watt lamp draw more current than a low watt lamp?
Power is measured in Watts, power (Watts) = E (volts) x I (current - amps) current is determined by the internal resistance (R) of the lightbulb, the lower the resistance the more current will flow. 120v x 0.5a = 60W 120V x 0.83a = 100W the 100W lightbulb will draw more current We also have Ohm's law: E(volts) = I (amps) x R (ohms) Household voltage stays the same at 120v we have for a 100w lamp: 120v = I x R R = 120v/0.83 amps R = 144.6 ohms for a 60w lamp: 120v = I x R R = 120v/0.5 amps R = 240 ohms The higher watt lamp has lower resistance.
What is the line voltage given the load voltage is 2000v and voltage regulation is 2 percent?
The line voltage in the usa is 120V if the 2000V is for a tube in a microwave oven it generally depends on a transformer and rectifier so the line voltage will go down about 2% to retain the output
What is the power rating for a radio that has 0.1 amps and standard voltage oe 120v?
12 watts
What is the power dissipated by a resistor that has 5 amps flowing through it with 120 volts applied?
The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).The power in a resistor (in watts) is simply the product of the current (in amperes) times the voltage (in volts).
What is the resistance of a clothes iron that draws a current of 12A at 120V?
By Ohm's Law Voltage = Current x Resistance R = V / I = 120 / 12 = 10 Ohms
