Question

A 3 Ω, a 5 Ω, and a

4 Ω resistor are connected in series

across a battery. The voltage drop

across a 3 Ω resistor is 6V. What is

the battery voltage?​

Answer 1

Answer:

24

Explanation:

formula :

V=IR

R = R1+R2+R3

= 3+5+4

= 12

I = V/R

= 6/3

= 2A

battery voltage V= I R

= 2*12

= 24
