Parallel DC circuits

Hence, NI Multisim is an essential software that enables the user to observe the operation through simulation without performing that operation.
Simulation software is play an important role in understanding how circuits operate in electronics. Electronic simulation software applies mathematical models to show the behaviour of an actual electric circuit. Electronics simulators include Circuitlogix, electronic work bench, NI Multisim among others. By simulating a circuit’s behaviour and response before building it, greatly improves efficiency and provides insights and relevant information concerning the behaviour and stability of electronics circuit designs.
In many electrical circuits, it is important to determine the rate at which electrical energy is transferred into other forms of energy. To calculate power P for electrical appliances, we find the product of the current (A) through it and the Potential difference (V) across it. Thus,
For resistors in series, the same current flows each of the resistors whereas the total sum of the voltage across each resistor equals to the total voltage applied. Therefore, the combined resistance is given by
To study various waveforms on the DSO, the 3MHz Function Generator (TG300 Series) was connected to CH1 of DSO (Tektronix) using BNC leads. A sine wave of 1 kHz frequency and a root mean square voltage of 1.4145V was displayed on the screen. The period of the sine wave was determined using equation 1 in the introduction. Furthermore, the peak to peak voltage of a sine wave was measured and recorded as required. The waveforms and its FFT graphs were then printed out using the PC communication software.
Similarly, a square wave with parameters 2 kHz frequency and 2Vpeak was shown on the screen. The period of the waveforms and the peak-to-peak voltages were determined. The FFT graphs were printed out as required. The above procedure was repeated for 1.5 kHz, 2Vpeak ...Show more


One of the ways of understanding electrical circuits is through simulation software. In this Lab, NI Multisim software is used to study…

Current flow in a circuit (purely resistive and restive-capacitive
The current may cause effects such as heating or even induce magnetic fields preferably used for generators, motors and inductors. Current generally flows from the positive terminal towards the negative terminal of battery and there is voltage drop across the electrical elements in the circuit due to resistance, reactance or inductance.
