In the circuit of Fig., assume that the diodes are ideal and the meter is an average indicating ammeter. The ammeter will read

In Fig., A₁, A₂ and A₃ are ideal ammeters. If A₂ and A₃ read 3 A and 4 A respectively, then A₁ should read

A DC voltage source is connected across a series R-L-C circuit. Under steady-state conditions, the applied DC voltage drops entirely across the

A series $$R$$-$$L$$-$$C$$ circuit has a $$Q$$ of $$100$$ and an impedance of $$\left( {100 + j0} \right)\,\Omega $$ at its resonant angular frequency of $${10^7}$$ rad/sec. The values of $$R$$ and $$L$$ are: $$R=$$ ______ ohms. $$L=$$ ________Henries.
