What else can I help you with?
How can you tell if a 4 channel 800 watt car amplifier is 2ohms or 4 ohms?
Your 4 channel amplifier has neither a 4 ohms nor a 8 ohms output impedance. The output impedance will be smaller than 0.5 ohms. In audio we only use amplifier and loudpeaker bridging. Don't believe the myth of matching. Scroll down to related links and look at "Impedance bridging - Wikipedia".
What does a coefficient tell you in science?
Coefficients are, in general, a number that is a factor of a term in a formula. It is constant, and so doesn't contain any of the variables of the formula. For example for a fixed resistor with 5 ohms, the voltage V= 5I (I=current) the number 5 is a coefficient. Other formulae have other coefficients, and particular measurements may be named coefficients. Eg the coefficient of friction. tl;dr They are numbers, different coefficients tell you different things
What are the basic principles of ohm's law?
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. This can be expressed as the formula I V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms.
What is the difference between unit and quantity?
It is the rate.
What is a real world example of solution conductivity?
A PH meter measures conductivity to tell the amount of Hydrogen in a solution. A conductivity meter is used to measure the purity of water in ohms. A battery is a great example of solution conductivity at work.
What is the value of a resistor marked with Brown Yellow White Black bands?
149 ohms, I believe.
What are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
What is the value in ohms of a resistor colored brown red yellow gold?
The first band, brown, indicates the digit 1.The second band, red, indicates the digit 2.The third band indicates the multiplier. For yellow, this is 10000.12x10000 = 120,000 ohms.The last band is an indication of the tolerance of the resistor; gold means the actual value is within 5% of the stated value.
Is the resistance value of the resistor 22000 ohms 22 megohm resistor?
22Kiloohm is 22,000 ohms 22megohm is 22,000,000 ohms Kilo is a thousand meg/mega is a million
What is color code of 2.2ohms resistor?
Thecolorcode of 2.2 ohms resistor is red red yellow silver.
What is the relation between the size of the resistor and its value?
There is no relation between the resistor's ohms value and its size. The power of the resistor can be seen by its size. If the power is too small, the resistor can be destroyed.
In a parallel circuit the smallest resistor is 500 ohms. What is the largest value this parallel circuit can have?
500 ohms.
What is the value of Gold of a resistor?
red = 2violet = 7silver = 0.01gold = 5%The value is 27 * 0.01 ohms 5% or 0.27 ohms 5%
What is the value of a 4-band resistor with yellow violet orange and silver as the bands?
47000 ohms with a 10% tolerance Yellow = 4 Violet = 7 Orange = 1000 (this is the multiplier) Silver = 10% tolerance
Does an open resistor measure 0 ohms?
No, an open resistor has a value of infinity. An open resistor typically will measure over 900 Megohms. A zero ohm resistor is exactly that, and will measure zero ohms. They are typically surface-mount devices.
Is resistor measured in amps?
No, resistors are measured in ohms, not amps. Ohms represent the resistance offered by the resistor to the flow of current, whereas amps (amperes) represent the measure of current flowing through a circuit.
When Resister is 120 volts and the current through the resister is 0.5 Amps determine the value of the resistor in ohms?
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
