Question

A 9V battery is attached to 6Ω and 3Ω resistor. What is the voltage going to the 3Ω resistor?

1 V
3 V
9 V
2 V
4.5 V
It is a short circuit

Answer 1

Voltage across 3 resistor =13.5v

Step-by-step explanation:

Voltage=resistance *Current

But we don't have total current, so we must find total current

Current =v/R

Current=9/2

Current =4.5I

From

V=R*I

V=3*4.5

V=13.5v
