Hydroelectric power is a renewable energy source that generates electricity through the movement of water, typically from rivers or dams. It is known for being a low-emission energy source and can provide a reliable and consistent power supply. However, it can also have significant environmental impacts, such as disrupting local ecosystems and displacing communities. Therefore, any statement claiming that hydroelectric power has no environmental effects or is entirely without drawbacks would be false.
What else can I help you with?
True power divided by apparent power?
Real Power: The actual power in Watts or K-Watts in AC or DC Circuits Apparent power: The Power in Inductive or Capacitive Circuits have Phase Lag & Lead measured in Volt Amperes VA or Kilo Volt Amperes KVA
Which of the statements concerning parallel circuits is NOT true?
D. The total resistance is equal to the lowest resistance in the circuit
What is the ratio of apparent power to true power?
The ratio of apparent power to true power is called 'admittance', expressed in siemens. Admittance is the inverse of impedance.
Why power factor expressed in cosine angle?
The vector-relationship between apparent power, true power, and reactive power is represented by a right-angled triangle, whose hypotenuse represents apparent power and whose adjacent represents true power. Since power factor is defined as 'the ratio of true power to apparent power', you will find that this ratio corresponds to the cosine of the angle between them.
What is the apparent power of an RLC parallel circuit if the true power of the resistor is 4800 watts the reative power of the inductor is 7200 and the reactive power of the capacitor is 3600?
Apparent power is the vectorial sum of the true power and reactive power. In this case, the total reactive power is the difference between 7200 var and 3600 var -i.e. 3600 var.So you can now use the equation,(apparent power)2 = (true power)2 + (total reactive power)2,to determine your answer.
