Your RL circuit has a characteristic time constant of 20.0 ns, and a resistance of 5.00 MΩ.

(a) What is the inductance of the circuit?

(b) What resistance would give you a 1.00 ns time constant, perhaps for a quick response in an oscilloscope?

True or false, and why?

1. A circuit that includes resistors, capacitors, and inductancesin parallel is called an RLC circuit.

2. When capacitors and inductances are introduced into a DCcircuit, we get an AC circuit.

3. When an inductance is connected to a DC power source, thecurrent flowing through it decreases exponentially with time.

4. As a capacitor charges, the voltage across decreases.

5. The rms-current in an RL-circuit is the peak current divided bythe reactance.

6. In an RL-circuit, the current and the voltage are inphase.

7. The higher the frequency of the AC voltage source in anRL-circuit, the higher the currents.

8. In a circuit with an AC power source and an inductance inseries, the inductive reactance takes the place of the resistance.
