A series circuit consists of a non-inductive resistor of
10 Ω, an inductor having a reactance of 50 Ω and a
capacitor having a reactance of 30 Ω. It is connected to
a 230 V a.c. supply. Calculate: (a) the current; (b) the
voltage across each component. Draw to scale a phasor
diagram showing the supply voltage and current and
the voltage across each component.
