Power in Electrical Circuits

The video tutorial explains how to solve a learning assessment problem involving power calculation in a circuit. It introduces the problem, describes the elements involved, and explains the power formulas and the Intelligence Theorem. The tutorial then applies the theorem to calculate power for each element, using the passive convention to determine if elements are absorbing or supplying power. Finally, it verifies the results using the Intelligence Theorem, ensuring that the power supplied equals the power consumed.

What is the voltage and current rating of the constant current source in the circuit?

• 12 volts and 3 amperes

• 18 volts and 3 amperes

• 6 volts and 3 amperes

• 12 volts and 6 amperes

According to the Intelligence Theorem, what is the relationship between power supplied and power consumed in a closed circuit?

• Power supplied is unrelated to power consumed

• Power supplied equals power consumed

• Power supplied is less than power consumed

• Power supplied is greater than power consumed

What is the power consumed by the element with 18 volts and 3 amperes?

• 54 watts

• 36 watts

• 18 watts

• 72 watts

If the current enters the positive side of an element, what does it indicate about the power?

• The element is neutral

• The element is malfunctioning

• The element is supplying power

• The element is absorbing power

How much power is supplied by the 3 ampere constant current source with 12 volts?

• 72 watts

• 18 watts

• 54 watts

• 36 watts

What is the power supplied by the element with 6 volts and -3 amperes?

• 72 watts

• 54 watts

• 36 watts

• 18 watts

What does a negative sign in power calculation indicate?

• Power is being supplied

• Power is being absorbed

• Power is zero

• Power is infinite

What is the total power delivered by the sources in the circuit?

• 54 watts

• 72 watts

• 36 watts

• 18 watts

What is the total power consumed by the elements in the circuit?

• 54 watts

• 36 watts

• 72 watts

• 18 watts

What does the Intelligence Theorem state when the power supplied equals the power consumed?

• The circuit is malfunctioning

• The circuit is closed

• The circuit is balanced

• The circuit is open
