Hello people. Im not very good with electrical circuits and i was wondering if someone out there could take a few mins to help me with this problem. In the attached cicuit diagram i need to find the value of the first resistor. I hope i drew it clear enough to understand. When the switch is closed the voltmeter shows 8 volts, but when the switch is open the switch it reads 8 volts.
If someone could be kind enough to explain a solution to me i would be really thankful.
Thanks
