Will 8 ohm speaker work with 4 ohm bass guitar amplifier?
Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.
Can you run 4ohm resistor to make 4 ohms speakers 2 ohm?
Yes, you can safely use a 4 ohm amp with one 8 ohm speaker, but you will not achieve full power. The 4 ohm amp is designed to supply a certain voltage into a 4 ohm speaker. Supplying that same voltage to an 8 ohm speaker will result in half the power, or -3dB. For maximum power, use a 4 ohm speaker, or two 8 ohm speakers in parallel.
Can a 4 ohm cabinet be changed to 8 ohm?
Its not recommended. A four ohm speaker cabinet can be changed into an eight ohm speaker cabinet, if you have enough speakers in the cabinet in parallel that can be rewired in series. Unless you have a high end cabinet, the likelihood of this is small.Two four ohm cabinets, however, in series will be eight ohms. Keep in mind, however, that doubling the resistance will halve the current, which will quarter the power. Also, changing the impedance of a speaker system will change the frequency response, because often the filters are tuned with resistors.
What is the current through the 150 ohm resistor?
It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).
How do you calculate current required?
By Ohm's Law.... Voltage equals Current times Resistance (V=I*R) So if given the voltage and resistance of a system and applying algebra I=V/R .
Will 8 ohm speaker work with 4 ohm bass guitar amplifier?
Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.
How do you compute for voltage if current and resistance is given?
Voltage = Current * Resistance (Ohm's law)
What is the difference between 2 ohm's and 4 ohm's related to subwoofers and sound?
Speakers need to be matched to the amplifier. This will allow maximum dynamic range of power before distortion. In extreme cases, overloading an amplifier can damage it. A 4 ohm speaker requires a certain voltage and current to achieve a certain power. A 2 ohm speaker will require less voltage or greater current (ratio the square root of 2) to achieve the same power. The decision is based on the system design, including the design of the cross-over network, if there is one.
Will a 4 ohms speaker work with a 16 ohms amplifier?
An amplifier that is rated to drive a 16 ohm load will not perform well if a 4 ohm load is applied to it. The output rating is calculated to allow the highest power output from the amplifier. If a 4 ohm speaker is used instead of the recommended 16 ohm speaker, the current output will be far higher for a given output voltage. Although the amplifier will drive the speaker at low levels, as the volume is increased, the output current may rise to the point where it will damage output transistors or perhaps the main power supply. Some 16 ohm rated amplifiers may well handle 4 ohm speakers without damage but the only way to find out is to try it - meaning a dead amplifier if the test isn't successful. So, just like my previous answer (what happened to it?), the answer is YES but not as well.
What ohm speaker is best?
take a 2 ohm bridge into 1 ohm
What is the difference between a 8 ohm speaker and 12 ohm speaker?
Study ohms law to get your head around it.
How do i Make a 8 ohm speaker 16 ohm?
You can't change the ohm load of a speaker. What you can do, is get a second 8 ohm speaker to run with that speakers in series and you will get a total ohm load of 16 ohms.To run them in series, simply wire the positive terminal of one speaker to the negative of the other speaker. One speaker will have an open positive terminal which you wire to the positive terminal on the amp, and same goes for the negative on the other speaker (to the amp's negative terminal of course).
What is the formula of calculating effective current if resistor and voltage is given?
I = E/R or Current = Voltage/Resistance (Ohm's Law)
Can resistance be added to speakers to make a 4 ohm speaker have an 8 ohm load?
You "can" add a four ohm resistor in series with a four ohm speaker, and make it look like an eight ohm speaker, however, the frequency response will not be the same. It is better to use to correct speaker for the amplifier, or use two four ohm speakers in parallel. That resistors power rating must exceed the rating of the speaker. Half the from the amplifier will go to the speaker, while half will go to the resistor, making it get quite hot.
Can you run 4ohm resistor to make 4 ohms speakers 2 ohm?
Yes, you can safely use a 4 ohm amp with one 8 ohm speaker, but you will not achieve full power. The 4 ohm amp is designed to supply a certain voltage into a 4 ohm speaker. Supplying that same voltage to an 8 ohm speaker will result in half the power, or -3dB. For maximum power, use a 4 ohm speaker, or two 8 ohm speakers in parallel.
Why does ohm's matter with speakers?
the vibration produced in the coil of a speaker is due to current passing through it hence it obey ohms law
What is the unit of the resistors?
Resistor values are given in ohms. A value may be selected to deliver a specific current at a given voltage. This is given in what is known as Ohm's Law where: Voltage (V) = Current (A) X Resistance (Ohm) A 12ohm resistor placed across a 12V battery would pass 1Amp of current and put out 12W of heat.
