When connected to the DC power source, the current flows through the circuit. The potential difference increases while the capacitor is being charged. When the voltage on the terminals is of the capacitors is equal to the power supply voltage, the capacitor is fully charged. When the circuit is disconnected from the power supply, the capacitor is said to be discharging through the resistors. The voltage across the circuits then drops gradually until it is zero.
At first, there is very little charge in the circuit. When power is supplied from the DC source, a charge builds up in the both the resistors and the capacitors. It is noted that as the charge increases in the circuit, the current recorded on the circuit gets smaller.
From the experiment carried out above, we can learn that the changes in both the voltage and current in a multisim circuit when charging and discharging. The charge Q in a circuit is dependent on the amount of voltage present and in turn this influences the current measured on the circuit. When the amount of charge gets larger, the amount of current measured gets smaller. When discharging, the voltage across the resistors and the capacitors drops gradually until it reduces to zero. The phase angles of both current and the voltage in this circuit have equal but opposite magnitude. The tests carried out in the lab and through simulation of the multisim circuit have been used to demonstrate that these conclusions are true.
In conclusion, it has the concept of charging and recharging of multisim circuits has been well understood and all the factors that influence the obtained results have been identified hence the objective has been fully
