In DC power supply feeds both polarized and non-polarized are used and safe as long as polarized capacitors are inserted correctly and no capacitor is exposed to a voltage beyond its rating. In AC power feeds non-polarized capacitors are mandatory, and if connected to AC mains they need to be X or Y rated for safety reasons.

Can I put multiple resistors in series to get higher resistance?
For instance a 30k resistor is not an E12 series value, but you can obtain it by putting two 15k resistors in series ; to allow a higher voltage. 0603 resistors have a working voltage of 50V, So if you want to use them in a 70V circuit you''ll have to place at least two of them in series. Care should be taken if you pick unequal values.

What is a resistor and a capacitor?
Resistors, capacitors, and inductors are not only classic building blocks of circuits. They inform us about the nature of the properties of resistance, capacitance, and inductance. Even a bare wire has some resistance, some capacitance, and some inductance.
Can a capacitor be charged without a resistor?
Without a load, current will not flow through a circuit, and will thus not charge a capacitor in the circuit. Instead of using a resistor as a load in order to charge a capacitor, any other load can be implemented. If a resistor is not available, a light bulb of appropriate voltage may be used.
