It’s a good exercise to get used to solving these kind of problems and to understand the principles of circuits.
## Which resistance is the worst?
The resistance of a resistor has a very bad effect on the direct current flowing through the circuit.
If the resistor is very small, a large amount of current will pass through it. If it's large, the DC will flow less in the circuit.
The resistance of a very small or a very large resistor will have almost no effect on the AC voltage.
So, the resi
