Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is

The size of this voltage difference ( V ) is related to the charges on the two plates (Q): Q = C ⋅ V. The constant C is called the capacitance. It determines how much of a charge difference the capacitor holds when a certain voltage is applied. If a capacitor has very high capacitance, then a small difference in plate voltage will lead to a

Current Limiting Resistor
A current limiting resistor is a resistor that is used to reduce the current in a circuit. A simple example is a resistor in series with an LED. You would usually want to have a current limiting resistor in series with your LED so that you can control the amount of current through the LED. If too much current is going through your LED, it will
Calculate Charge time of capacitor with current limiting power
At what capacitor voltage does that require 1 A or more? Since R1 is 1 Ω, 1 A thru it causes a 1 V drop. If the supply is 10 V and R1 drops 1 V, then there must be 9 V on the capacitor when the current is 1 A. If the capacitor voltage is lower, then the voltage on R1 must be higher, which means the supply has to source more than 1 A.

Capacitor vs. Resistor: What''s the Difference?
Capacitors and resistors both control electrical current, but they have different applications. Resistors are used to reduce or limit the flow of current, while capacitors are used to store energy. As a result, resistors dissipate energy as heat whereas capacitors do not. Another key difference between capacitors and resistors is
