Question

A 600 ohm and 1200 ohm resistor are connected in series with a 12 V battery. What is the voltage across the 2200 ohm
resistor?​

Answer 1

R ( resultant) = 600 + 1200 = 1800 ohm

V = IR

I = 12 / 1800

I = 1/50 A

So, across 1200 ohm resistor,

Voltage = IR = ( 1/50 )× ( 1200 ) = 24 V

V = 24 V
