What is the voltage across R2 with an input voltage of 5.0V and resistors R1 = 1.5 kiloohms and R2 = 0.5 kiloohms? Calculate this value in volts.

Respuesta :

Answer:

1.25 V

Explanation:

Total resistance = R₁ +R₂ = 1.5 +0.5

2 x 10³ ohm.

Current in the circuit = Volt / resistance

= [tex]\frac{5}{2\times 10^3}[/tex]

= 2.5 x 10⁻³ A

Voltage drop across R₂ = Current x resistance of R₂

= 2.5 X 10⁻³ X 0.5

= 1.25 V.
