What is the voltage across r2 with an input voltage of 8.0v and resistors r1 = 2.0 kiloohms and r2 = 4.5 kiloohms? calculate this value in volts.

in series  voltage = 5.538 V

in parallel voltage = 8 V

Explanation:

given data

voltage = 8.0V

resistors R1 = 2.0 kilo ohms

resistors R2 = 4.5 kilo ohms

to find out

voltage

solution

we know if the resistors in series

voltage formula is

voltage = V R2 / R1+R2   1

put here all value

voltage = 8(4.5) / (2+4.5)

voltage = 5.538 V

and

if the resistors in parallel

voltage is same across resistor i.e 8 V

the body's situation won't change the forces are equal opposit and on the same body
