IB DP Physics: HL復(fù)習(xí)筆記11.3.7 Discharge Calculations
Capacitor Discharge Equation The?time constant?is used in the exponential decay equations for the current, charge or potential difference (p.d) for a capacitor discharging through a resistor These ...
IB DP Physics: HL復(fù)習(xí)筆記11.3.6 Capacitor Charge & Discharge
Exponential Discharge of a Capacitor Charging Capacitors are charged by a?power supply?(eg. a battery) When charging, the electrons are pulled from the plate connected to the positive terminal of t...
IB DP Physics: HL復(fù)習(xí)筆記11.3.5 Energy Stored in a Capacitor
Energy Stored in a Capacitor When charging a capacitor, the power supply pushes electrons from the positive to the negative plate It therefore does?work?on the electrons and?electrical energy?becom...
IB DP Physics: HL復(fù)習(xí)筆記11.3.4 The Time Constant
The Time Constant The time constant of a capacitor discharging through a resistor is a measure of how long it takes for the capacitor to discharge The definition of the time constant is: The time t...
IB DP Physics: HL復(fù)習(xí)筆記11.3.3 Capacitors in Series & Parallel
Capacitors in Series & Parallel Capacitors can be combined in series and parallel circuits The combined?capacitance?depends on whether the capacitors are connected in series or parallel Capacit...
IB DP Physics: HL復(fù)習(xí)筆記11.3.2 Dielectric Materials
Dielectric Materials Permittivity is the measure of how easy it is to generate an electric field in a certain material The relativity permittivity?εr?is sometimes known as the?dielectric constant F...
IB DP Physics: HL復(fù)習(xí)筆記11.3.1 Capacitance
Capacitance Capacitors are electrical devices used to store energy in electronic circuits, commonly for a backup release of energy if the power fails They are in the form of two conductive metal pl...
IB DP Physics: HL復(fù)習(xí)筆記11.2.9 Capacitors & Diode Bridges
Capacitors & Diode Bridges In?rectification, to produce a steady?direct current? or voltage from an?alternating current??or voltage, a?smoothing capacitor?is necessary Smoothing is defined as: ...
