RC - Circuit

In RC-Circuit,there are a battery,a capacitance,and a resistor. When the circuit is close access, the capacitance begins to store charge. When the circuit takes out the battery, and forms close access, the capacitance is instead of battery to release charge. In this activity, the lab is instead of resistor. When we turn on the the battery, the lab is from bright to turn off because charge store in the capacitance.

When we used two capacitance in the circuit, and the two capacitance were series, the lab would turn off later than the fist activity because the series capacitance make the total capacitance become small. The capacitance became small, so it stored less charge than the fist activity,and the lab could bright longer than the fist activity.

When the two capacitance were parallel, the lab would turn off faster because the parallel capacitance made the total capacitance become large. It could store more charge.

 This picture showed the capacitance was charge in RC-Circuit.

This picture showed the capacitance was discharge in RC-Circuit.

This graph showed the voltage of capacitance vs. time in charge of RC-Circuit and discharge of RC-Circuit.

Therefore the Voltage have a relationship with the capacitance and resistor

The last picture showed the current and voltage of capacitance vs. time, and the current and voltage of resistor vs. time.
