jännitejakajat
Jännitejakaja, or voltage divider in English, is a simple passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). It is typically constructed using two or more resistors in series. The most basic form consists of two resistors, R1 and R2, connected in series across a voltage source. The input voltage Vin is applied across the series combination of R1 and R2, and the output voltage Vout is taken across R2.
The principle behind the voltage divider is Ohm's Law. Since the resistors are in series, the same
Voltage dividers have numerous applications in electronics. They are commonly used to step down a higher voltage
