A voltage divider produces an output voltage that's a fraction of its input voltage, determined by the two resistors R1 and R2.
The output voltage is determined by Vo=Vi(R2/R1+R2).
Resistor dividers are often used to generate reference voltages or as level shifters; their high impedance means that attempting to draw significant current from them will cause the voltage to vary.

Launched in 2013, Telegram allows users to broadcast messages to a following via “channels”, or create public and private groups that are simple for others to access. Users can also send and receive large data files, including text and zip files, directly via the app.The platform said it has more than 500m active users, and topped 1bn downloads in August, according to data from SensorTower.
A project of our size needs at least a few hundred million dollars per year to keep going,” Mr. Durov wrote in his public channel on Telegram late last year. “While doing that, we will remain independent and stay true to our values, redefining how a tech company should operate.
