The amount of data required to watch a live Physics Wallah lecture can vary depending on several factors, such as the video quality, duration of the lecture, and the streaming platform being used.
Video quality is typically measured in terms of resolution (e.g., 240p, 480p, 720p, 1080p, etc.). Higher resolution videos offer better visual clarity but require more data to stream. The specific bitrate of the video, which determines the amount of data transferred per second, also plays a role.
As an estimate, let's consider common video resolutions and their approximate data usage per hour for streaming:
- 240p (Low Quality): Roughly 150-250 MB per hour.
- 480p (Standard Definition): Approximately 300-500 MB per hour.
- 720p (High Definition): Around 700 MB to 1.2 GB per hour.
- 1080p (Full High Definition): Approximately 1.5 GB to 3 GB per hour.
- 4K (Ultra High Definition): Roughly 7 GB to 20 GB per hour.
These figures are rough estimates and can vary depending on compression techniques used, the complexity of the video content, and other factors. Additionally, live streaming may have slightly higher data requirements due to real-time encoding and transmission.
To determine the precise data usage for a specific Physics Wallah lecture, it is recommended to monitor the data consumption during a test stream or check with the streaming platform to see if they provide data usage statistics.
