... Ans: We can combine the impedance of the inductor in series with the resistor to form the total impedance in the circuit. The current is then the voltage source divided by this impedance. We can then find the voltage across the inductor and the resistor in turn by multiplying the impedance of each e ...

Valve RF amplifier
A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
