Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
How much current would an applied voltage of 10 volts cause through a resistance of 5 ohms?
10 volts applied to 5 ohms would cause a current flow of 2 amperes. Current = voltage divided by resistance.
What are linear wave Shaping circuits?
if a sinusoidal voltage is applied to linear circuit the output voltage is also sinusoidal in nature as far as the waveform is concerned the amplitude of input signal may change and there may be phase displacement between input voltages and output voltages
How can calculate resistance for negative dc voltage?
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
What is the resistance of the heating element of an electric iron it the ampere draw is 8 amperes when 115 volts are applied?
Using Ohm's Law (E = I R) Voltage = Current x Resistance or switch around to get R = E / I: 115 volts / 8 Amperes = 14.375 Ohms The above is correct for DC current but is close enough to be used for AC current.
How many watts are consumed by a light bulb if 1.2 amperes are measured when 12 volts are applied?
144 watts <<>> The formula to find watts is W = A x V. Watts =Amps x Volts.
How many watts are consumed by 1.25 amperes?
The number of watts produced by a current of 1.25 amperes can only be known if you also know either the applied voltage which caused that current to flow (W=I x E); or if you know the resistance through which the current flows. (W= I2 R).
Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
What relation of voltage and current?
Current is directionally proportional to the applied voltage and inversely proportional to the resistance of the circuit. <<>> EMF (electromotive force) is measured in Volts. Current is measured in Amperes. Like water pipes, EMF (or voltage) is the "push" or pressure in an electrical circuit. Current is like the gallons per minute . . . it is the "amount" of electrical flow.
Can 550Ma kill?
If you mean 550 mega-amperes (as you wrote it, million amperes) it not only will kill a person, it will vaporize a person!If you mean 550 milliamperes that depends on how it is applied to a person:Currents of only 10 microamperes (millionths of an ampere) can kill if applied directly to the heart.Currents of more than 30 milliamperes of AC (rms, 60 Hz) or 300 milliamps of DC can kill if applied to the skin.Note: milliamperes is written mA, mega-amperes is written MA.
Are volts a kind of amp?
If the question refers to Voltage (volts) and Amperes (amp), then the answer is no! If you imagine holding a garden hose with the spray at the end closed preventing water flow, but the tap (valve) at the other end open, there will be a pressure of water in the hose, but no water flow. The pressure in the hose (measured in Bar) is similar to the voltage applied to a cable. When the spray is operated there is a flow of water through the hose, this is similar to the current flowing through a cable and its load when a switch is closed, the current is measured in amperes.
Can the total of the voltage drop across the loads of a series circuit ever exceed the total of the source voltages applied to that circuit?
no
How are lower voltages combined into higher voltages for transmission?
Low voltages are not 'combined into higher voltages' for transmission! The lower voltage (e.g. the voltage generated at a power station) is applied to the primary winding of a large power transformer, and the required higher transmission voltage then appears across the transformer's secondary winding. The magnitude of the secondary voltage is determined by the turns ratio of the transformer's windings.
How is Physics applied at home?
Physics is the study of the nature and properties of matter and energy. At home, it is applied in how much energy is consumed by the appliances, how much heat is applied when cooking and the work done in household chores.
Can alcohol alter heat dissipation?
Either consumed or applied to the skin, alcohol increases heat dissipation.
How do you calculate current flow transformer when 240 Vrms is supply?
The secondary current of a transformer is determined by the load and the secondary voltage applied to that load, and this, in turn, will determine the primary current by the inverse of the turns ratio. However, if you are asking about a transformer's rated secondary and primary currents, then you need to divide the transformer's apparent power rating (expressed in volt amperes) by the rated secondary and primary voltages respectively.
What is the Power dissipated from a 0.5A current through a 5ohm resistor?
The current I = 0.18257 amperes. Scroll down to related links and look at "Electrical voltage V, amperage I, resistivity R, impedance Z, wattage P".
