Charge and discharge voltage and current graphs for capacitors. Capacitor charge and discharge graphs are exponential curves. in the above circuit it would be able to store more charge. As a result, it would take longer to charge up to the supply voltage during charging and longer to lose all its charge when discharging.
Graphs of variation of current, p.d and charge with time for a capacitor charging through a battery The capacitor charges when connected to terminal P and discharges when connected to terminal Q Graphs of variation of current, p.d and charge with time for a capacitor discharging through a resistor
throughout charging, the rate of flow of charge will not be linear.At the start, the current will be at its highest but will graduall decrease to zero. The following graphs summarise capacitor charge. The potential diffe ence and charge graphs look the same because they are proportional.You can also see that the gra
capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the c pacitor is fully discharged as there is no charge stored across it.The rate of decrease of the potential difference an the charge will again be proportional to the value o
Calculate the mean voltage and mean current for each time. charging began (s), R is the resistance of the fixed resistor and C is the capacitance of the capacitor. 0 the initial current. The area under the I-t graph gives the charge stored by the capacitor. Connect both a voltage sensor and current sensor to a data logger.
Switch the switch to the opposite position and start the stop clock. the capacitor has fully discharged. Plot a graph of voltage against time for the discharging of the capacitor, and use it to determine the time constant of the capacitor.
