R e s i s t o r :
To differentiate the units of resistors, such symbol as K is
used: the symbol K means 1000 ohm and the resistor with-
out any symbol is ohm-type resistor.
. Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
pacitor without such a symbol is microfarad. As to electro-
lytic capacitor, the expression "capacitance/withstand
voltage " is used.
