What is the approximate peak value of an alternating current producing 4 times the heat produced?
Hence, answer is (3) 5.6 A.
What is the approximate value of an alternating current producing 4 times the heat produced per second by a steady current of 2 A in a resistor?
Therefore, 2×2= 4 Amp AC (rms) will be required to produce four times heat. Peak value of 4 Amp (rms) current = 1.414×4=5.656 Amp.
What is the peak value of AC current?
√2 times
The peak value of alternating current is √2 times the root mean square value of the alternating current.
What is the equation of alternating current?
Key Equations
| AC voltage | v=V0sinωt |
|---|---|
| rms current | Irms=I0√2 |
| inductive reactance | V0I0=ωL=XL |
| Phase angle of an RLC series circuit | ϕ=tan−1XL−XCR |
| AC version of Ohm’s law | I0=V0Z |
What is alternating current write its peak and average value?
Definition: The maximum value attained by an alternating quantity during one cycle is called its Peak value. It is also known as the maximum value or amplitude or crest value. The sinusoidal alternating quantity obtains its peak value at 90 degrees as shown in the figure below.
What is peak to peak?
Definition of ‘peak-to-peak value’ Peak-to-peak value is the maximum voltage change occurring during one cycle of alternating voltage or current. The peak-to-peak value of an AC voltage is defined as the difference between its positive peak and its negative peak.
What is the average value of alternating current over a cycle?
zero
The mean or average value of AC over a complete cycle is zero because it contains positive half cycle and negative half cycle of the physical quantity.
What is peak making current?
making current is a peak value attain at first cycle when the circuit breaker is close. the making current rating is expressed in “peak” value of the maximum ac current it can safely close on that’s why it is always have higher value than breaking current.
What is alternating current in AC circuit?
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Audio and radio signals carried on electrical wires are also examples of alternating current.
What is peak to peak value?
Peak-to-peak value is the maximum voltage change occurring during one cycle of alternating voltage or current. The peak-to-peak value of an AC voltage is defined as the difference between its positive peak and its negative peak.
What is peak value and RMS value?
Note:Now, the peak value of current is defined as the maximum or highest value of current obtained in the one cycle. On the other hand, rms value of current is stated as the root mean square value of current that can be calculated when the dissipation in the resistor takes place as heat.
