What are watts amps and ohms?
ohms is a measure of resistance(R) in a circuit. Watts is a measure of the power(P), in this case lets assume it is the power used by the resistive element (lamp, heater etc). Power(watts)=Current(Amps)x Current(amps) x Resistance(ohms) or Resistance (ohms)=Power(W)/(current x current)
What is 97 k ohms in ohms?
97000ohms
How many watts are in 30 ohms?
Without specific information I cannot answer your question, however you can work it out. For a dc or single phase system you need to know 2 simple laws. P=V x I & V=I x R where: P = power in watts V = Voltage in Volts I = Current in Amps R=Resistance in Ohms we can therefore derive that since I=V/R and P=V x I then P=V x V/R or vsquared over R or in your case R = V(squared) / P = 12 x 12 / 30 = 144/30 = 4.8 ohms Now use the formula supplied with your voltage value, and you will know what the resistance is . See isn't math fun.
How many ohms in 800 watts?
4 ohms
Onvert 2.6k- ohms to base unit?
2600 ohms.
In Canada how many people are there per doctor?
470.... apparently :P
If you have 500 watts at 4 ohms how many watts do you have at 8 ohms?
250 watts approximatelyI assume you have a constant voltage supply. According to P=V^2/R => P*R=V^2, you have a 44.7 volt supply. If you change Resistance to 8 ohms, P=44.7^2/8 => P=250 watts.
Resistance of a 110V 100W lamp is?
The formula you are looking for is, R = Volts (squared)/Watts.
What is the difference between 6 ohms and 8 ohms?
Though it is tempting to say the difference is 2 ohms (8 ohms minus 2 ohms equals 6 ohms), lets look at some things. The 6 ohms is 3/4ths the resistance of the 8 ohms. If the resistances are loads, the 6 ohm load will draw 1/3rd more current than the 8 ohm load. The 8 ohm load will draw 3/4ths as much as the 6 ohm load. Those are some differences between 6 ohms and 8 ohms.
What are the electrical formulas for Volts Watts Current Resistance Ampere and Ohms?
Watts = Volts x Amps x Powerfactor Volts = Amps x Ohms Note: Power Factor is one for resistance loads and decreases toward zero for loads like motors. watts=VI=v*v/R=I*I*R volt=IR=square root of PR=P/I Ampere=V/R=P/V=square root of P/R ohms=V/I=V*V/P=P/I*I
What is 468 rounded to the nearest ten?
It is 470.
A 12 volts power supply is connected across two resistors R1 120 ohms and R2 470 ohms in series Calculate the potential difference across each when the negative terminal of supply is earthed explain?
Earthing of the negative terminal is a common practice and will not affect the potential across the resistors in the circuit. Calculating this is simple Ohm's Law. For a series circuit: R(total) = R1 + R2 + R3....... Rn In this case: Rt = 120 + 470 = 590 ohms Per ohms law E = I x R. We need to find the current flowing throught the circuit so: I = E/R = 12 / 590 = .0203 amps or 20.3 milliamps The potential across an individual resistor is calculated again by E = I x R So for R1 (120 ohms): E1 = I x R1 = .0203 x 120 = 2.44 V So for R2 (470 ohms): E2 = I x R2 = .0203 x 470 = 9.54 V For a check E = E1 + E2 = 2.44 + 9.54 = 11.98 The .02 difference is due to the use of significant figures.Another AnswerEarthing the negative terminal will have no affect on the potential DIFFERENCE across each resistor. 'Potential' exists at a single point. 'Potential difference' exists between two points.
