A voltage divider circuit is a simple circuit that takes a higher voltage and converts it into the lower voltage by using a pair of resistors. The ratio of output and input voltage should never be greater than 1. The general voltage divider circuit circuit is presented here.
Here Z₁, Z₂ are impedances. The impedances can be resistance R, capacitance C, or inductance L.
The basic types of voltage divides are along the lines:
Voltage Divider Rule:
Voltage dividers is the current passing through several devices connected in series is constant, but the voltage is divided between them in a circuit. RR divider is applicable to DC circuits. Here, impedance can be treated with zero resistivity and capacitance work as a gap in the circuit.
The general voltage divider formula for impedances is given as:
V₂ = Z₂ / (Z₁ + Z₂) * V₁
Here, V₁, V₂ are the amplitudes of the signals.
The voltage divider can be used in potentiometers, level shifters, resistive sensor reading and many more.
Question: Determine the output voltage of the voltage divider circuit whose resistances are 18 Ω and 24 Ω and the input voltage is 14 v.
Resistances R₁ = 18 Ω, R₂ = 24 Ω
Input voltage V₁ = 14 V
Voltage diver formula for output voltage is V₂ = R₂ / (R₁ + R₂) * V₁
V₂ = 24 / (24 + 18) * 14
Therefore, the output voltage is 8 v.
