举一反三
- If _____ voltage is applied across _____ circuit, _____ electric current will flow in _____ circuit.
- 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
- When measuring current, circuit power before connecting the meter in the circuit.
- The resistance value is infinite, the current passing through the resistance is always zero, and the voltage depends on the external circuit, then it is called as the short circuit state.
