What is the power of a parallel circuit with a resistance of 1000 ohms and a current of 0.03 amps?
.9 watts.
What is the power dissipated a resistor with a current of 0.02 amps and a resistance of 1000 ohms?
P = I^2 x R] P = 0.2^2 x 100 P = 4 W
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.
How many watts will be dissipated by a 30 ohm resistor with 12 volts applied?
P = IV Where: P = power in watts, I = Current, and V= Voltage Using ohms law: V = IR where V=Voltage, I = Current, and R= Resistance First solve for I, I = V/R, 12/30 = .4 Then use the power equation: P = .4*12 = 4.8 Watts
How do you determine shorted resistor?
A short circuit is an unexpected path of zero resistance between two nodes in a circuit. If you measure the resistance of a resistor, and find that is has zero ohms, but the resistor is supposed to be somthing else, such as 100 ohms, then you can conclude that the resistor is shorted. Keep in mind that the precision of the measurement might be critical. If the resistor is supposed to be 100 ohms, but you get zero ohms, then the answer is easy. If the resistor is 0.001 ohms, but you get zero ohms, then you have to consider the precision of the measurement, the resistance of the wires, etc.
Calculate the Power in watts dissipated by a resistor of 1000 ohms with 200 volts across it 2 watts 20 watts 40 watts 400 watts?
Ohms law states that V = I * R I = V/R R = V/I P = I*V Where V = Voltage, I=Current, R = Resistance and P = Power or Watt Watt is the amount of electricity flowing through a line which is (Voltage times Current in (Amperage) = Power or watts) To find the power dissipated by a resistor of 1000 ohms, we first find the current I. The voltage is given as 200volts. Therefore I = V/R = 200/1000 = 0.2Amps We said Power or Watt = I*V Therefore the Power or watts dissipated by a resistor of 1000 ohms will be P=I*V = 200*0.2 = 40 Watts
What is the power dissipated by a resistor with a current of 0.02 A adn a resistance of 1000 ohms?
Power dissipated = I2R 0.022 x 1000 = 0.4 watts
Calculate the resistor in a circuit having 12V source voltage and power dissipation of 10 W?
0.069444444444444444444444444444444444 ohms. P/E^2=R. P = power in watts. E = electricity in volts. R = resistance in ohms.
4 ohms equals how many watts?
Ohms does not equal watts. You need to know what voltage is across the resistor to determine how many watts it is drawing or how many watts the resistor should be rated for.Power is the voltage across the resistor SQUARED divided by the resistance. If this 4 ohm resistor has 12 volts across it then the watts power is (12 x 12) / 4 = 36 watts.1 Watt equals 1 Volt times 1 Amp.
What is the power of a parallel circuit with a resistance of 1000 ohms and a current of 0.03 amps?
.9 watts.
What is the current of a 25volt resistor?
Resistors are rated in ohms for their resistance value and in watts for the power they are capable of handling. They are not rated in volts or current.
What is the current 1 if the voltage is 100volts and the resistor is 10ohms?
Ohm's Law: Current is voltage divided by resistance.100 volts divided by 10 ohms is 10 amperes.This is also 1000 watts (power is voltage times current), so do not try it unless you have a resistor, a power supply, and a setup that can handle the power load!
What is the power dissipated by a resistor with a current of 0.02 A and a resistance of 1000 ohms?
Power = I2 R = (0.02)2 x (1,000) = 0.4 watt
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 the power dissipated a resistor with a current of 0.02 amps and a resistance of 1000 ohms?
P = I^2 x R] P = 0.2^2 x 100 P = 4 W
How can you work out the power of a resistor?
It depends what you mean by your question. Ohms Law is the key. Power in a resistor is wasted as heat. If a resistor has 1 volt across it and passes a current of 1 amp, it will consume/dissipate one Watt of power ,and must therefore have a resistance of one ohm. To work out the power rating of a resistor required, use V x I = P V is voltage I is current in Amps P is power in Watts R is resistance in ohms V=I X R. I=V/R R=V/I Ohms Law is the fundamental equation of electricity and must be understood before you can go further.
Formula for watts and amps?
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
