What gauge of wire must be used in homemade wind turbine?
You would need to know the maximum watts and voltage you could generate then go from there. In home use you use 12 gauge wire at 120 volts to handle up to 20 amps. 14 gauge for 15 amps. If you're operating in 12 volt it's a different ballgame.
How do you use capacitor in a sentence?
Capacitor is a noun, as in a person, place or thing. It is an electrical device. Ex: The capacitor failed and has to be replaced.
v=ir
Ohm's law states that , in a dc circuit the current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. It has the formula V=IR where I is the current and R is the resistance.
Should you worry about capacitor lead length in a circuit?
Capacitor lead length is a consideration in a circuit when the frequency involved is sufficient the make the parasitic capacitance and inductance of the leads important.
What is FT1 on electrical cable?
FT1 is one of three vertical flame tests. FT1 cables can be used in buildings that are rated combustible. For more information search you browser for Flame Test ratings
Great Question! There is a company from California that deals in electrical salvage material. I am not sure of the companies name but I am sure you can search for it online. They specialize in all items not manufactured today.
Where are gas insulated substations to be installed?
gas insulated substations are installed especially where floor area available is limited and maintenance cost is more
1.5 ohms. Two 3 ohm resistors in parallel.
If capacitors dont use ac current then how and why are they used in most appliances?
Capacitors resist a change in voltage, proportional to capacitance and current. This is called capacitive reactance. As a result, a capacitor in an AC circuit will create a leading phase angle, current relative to voltage. This, for example, can be used to help start a motor by creating two magnetic fields, one leading the other.
Is it ok to have the dot on a current transformer upside down?
You are probably referring to a 'polarity mark'. This is very important if the CT's burden requires current to flow through it in a particular direction in order to work properly. For example, it won't make any difference if the burden's an ammeter. But if the burden is, say, a wattmeter, then it's very important to observe the CT's polarity mark when it is wired, otherwise the wattmeter might read 'downscale' (backwards). It's also very important when the CT supplies protection relays.
If the neutral point is not earthed than the zero sequence current will not have any return path.It will be an open circuit for the zero sequence circuit.
How do you measure resistance in substation?
As we all know, Transformers are majorly used in substations. Transformers are specified with their Copper loss & Iron loss impedance (similar to resistance in DC circuits) which are generally considered with AC supply. Therefore, we can calculate the total impedance by
Here, you'll have to consider if the transmission is double circuited or else likewise.
When the current through a 12 k ohm resistor is 8 ma the power is?
Why transformer is only used instead of any other device?
A transformer is the primary device which transforms voltage to a higher or lower voltage. In electronics, capacitors and resistors perform this function.
What is Inductor transient response?
An inductor resists a change in current through the creation/destruction of the magnetic field around the inductor. In an IR Circuit, when the electromotive force (the battery voltage) changes, the inductor will create a voltage to oppose the change, causing the current flowing through the circuit to change gradually over time rather than instantaneously. In an ideal IR circuit, the induced voltage is initially equal and opposite to the change in electromotive force, and it decays exponentially, with a time constant proportional to the inductance of the circuit.
Is current the voltage multiplied by resistance?
No. V =
Voltage, I =
current, and R =
resistancein the simple equation: V=I*R. As well, V/I=R, and. V/R=I
so Current is voltage divided by resistance
Is wireless transmission possible for high voltage?
no, because baat aisi hai bhai agar voltage jyada hogi to connection toot jayega to wireless transmission kya ghanta hoga...... :D
Having a low voltage, or designed to work at low voltages.
(4 coulombs / 2 seconds) = 2 coulombs per second = 2 Amperes.
Why doesn't any current flow through the galvanometer in a balanced Wheatstone bridge?
There is no current flow through the galvanometer in a balanced Wheatstone bridge because, in the balanced state, the voltage on both terminals of the galvanometer is the same. Since the voltage differential in zero, there can be no current.
The greater the what the less current there is for a given voltage?
Resistance is probably the missing word. I = e/R. If R is greater, I is less.
The question cannot be answered. It would depend on what device you are using to do the converting. [edit] Well, in the simplest terms: Power (kW) = Power (HP) x 0.7457 Power (HP) = Power (kW) x 1.341
