For the sinusoidal steady-state circuit, ， the real power absorbed by 5 W resistor is 10W ， the power factor of the circuit is:/ananas/latex/p/149319
举一反三
- The circuit is in steady-state, when ， the switch is opened. Then is:/ananas/latex/p/149239
- In the circuit, N S contains independent sources. W hen =0 ， ； when ， ； then when ， v is:/ananas/latex/p/149299
- The power that an amplifier delivers to a load is equal to the difference between the power that the circuit draws from the power supply and the power that the circuit dissipates. ? 正确|错误
- The plus (+) and minus (-) signs in an electric circuit diagram are used to define . A: . voltage polarity B: . current direction C: . power flow D: . absorbed power
- In the circuit, contains independent sources, when ，then ；when ，then ；when , should be:/ananas/latex/p/106016
