Why does the capacitor have a resistor in parallel? What does it do?

First of all, electricity is very dangerous for human beings, because a lot of people die of electrocution, so how to protect the safety of electricity users is very important in this era of electricity. Resistance is placed behind capacitance in which have certain security considerations, we use the electrical appliances off when the voltage capacitance and not fully released, so this time if the human to touch the plug is the risk of electric shock, so if all these voltage light can be very good avoid such risks, then the resistance is played such a role, it gives the excess electricity is clean.

Second, we all know the role of resistance, is the name of the original intention, obstruct the flow of electricity, then the meaning of the capacitance is a container of electricity, so these two things together on the will become a kind of has a more powerful can hinder the role, here is bright red light to direct current (dc), but for alternating current (ac) is a bright green light can pass. The resistance also ACTS as a counterweight. If there is no resistance, the incoming voltage may create a backlog with the incoming voltage, so such a resistance is placed.
