Question

Write two limitations of the use of electrical impulses.

Answer 1

Step 1: Limitation 1 - Loss of Energy:
One of the key limitations of using electrical impulses is energy loss due to resistance in the conducting wires. As electrical impulses travel through the wires, some of the electrical energy is converted into heat due to the resistance of the material. This results in a loss of power, which reduces the efficiency of the system. The energy loss is especially significant when electrical impulses need to travel over long distances, which is common in power transmission systems. The use of thicker wires or more efficient conductors can reduce this loss, but it cannot be completely eliminated.

Step 2: Limitation 2 - Signal Degradation:
Another limitation of electrical impulses is signal degradation over long distances. As the electrical impulses travel through the medium (e.g., cables or wires), the signal strength can weaken due to factors such as resistance, capacitance, and inductance in the transmission medium. Additionally, external factors like electromagnetic interference (EMI) can further degrade the quality of the signal. This becomes particularly problematic for high-frequency signals, where even small losses in signal strength can lead to significant distortion or loss of information. In cases where the signal needs to travel over very long distances, amplifiers or repeaters are often required to boost the signal strength, which adds to the complexity and cost of the system.

Step 3: Conclusion:
While electrical impulses are widely used for transmitting power and signals, they come with limitations such as energy loss due to resistance in the wires and signal degradation over long distances. These factors must be managed effectively to ensure the efficient and reliable use of electrical impulses in various applications.
