What is capacitance? The 3 Effects of Capacitance - The 2-Minute Guru (s2e8)

In today's 2-Minute Guru, we use a 1000 X-Series oscilloscope to measure a capacitor and view the effects of capacitance on a basic electronic circuit consisting of a resistor and a capacitor.

See the three different effects capacitance has on electrical systems. Knowing the 3 effects of capacitance will help you learn how to properly use capacitors and how to identify capacitive influences in your systems.

Capacitors are the most common cause of capacitive effects, but capacitance is an inherent electrical property of basically every material.

So, what do capacitors do?

First, capacitors resist a voltage change by storing and releasing electrical charge. The ability of capacitors to store charge, based on the formula Q=CV, means that when a voltage is applied to the capacitor, it will start to store that energy instead of passing it through to the system. This can be used to create high pass and low pass filters.

Second, capacitors selectively filter frequency components of AC signals. Depending on the configuration, capacitors will filter high or low frequencies out of an electrical system. A capacitor allows high frequency components to pass through it and blocks out low frequency signal components.

Third, a capacitor changes the phase relation between voltage and current. In a capacitive circuit, the current leads the voltage. Capacitors change the phase by 90 degrees. When the capacitor is in parallel with a resistor, the phase shift is only 45 degrees.
