1. how does energy joule change as the circuit is left running? a) increases b) stays the same
Explain your answer.
2. how does power in watts change as the circuit is left running? a) increases b) stays the same
Explain your answer.
1. The energy joule stays the same as the circuit is left running because it is a measure of the total amount of energy used, and as long as the circuit is not adding or removing any components or energy sources, the energy used will remain constant.
2. The power in watts may increase or stay the same as the circuit is left running, depending on the type of circuit and the components being used. For example, if the circuit has a constant power source and fixed resistance, the power will stay the same. However, if the circuit has variable components, such as a variable resistance or changing voltage, then the power in watts may increase or decrease as the components change.
1. As the circuit is left running, the amount of energy in joules does not change. The unit joule is a measure of energy, and it represents the amount of work done or the amount of energy transferred. In a closed circuit, energy is conserved, meaning it remains constant. Therefore, the answer is (b) stays the same.
2. The power in watts also stays the same as the circuit is left running. Power is the rate at which energy is transferred or converted, and it is calculated by dividing the amount of energy by the time taken. Since the energy does not change and the time taken is continuously increasing as the circuit is left running, the power remains constant. Therefore, the answer is (b) stays the same.
