[QUOTE="Majid786, post: 113084, member: 8142"] Hi Doc, Apologies for that I shall make it clearer: The arrangement is as follows: [B]There are two resistors placed in parallel one value is not known and the other resistor has a value of 20 ohms. [/B] [B]There current that flow to the parallel resistors is 0.5A [/B] [B]Then there is also a single resistor connected in series which has a value of ohms . [/B] [B]The voltage supplied to the circuit is 30v . [/B] [B]The question is to find the value of the unknown resistor which is connected in parallel with the 20Ohm resistor. [/B] [B]The answer given: 2.86 ohms [/B] [B]Ref: book Electrical Installations Calculations: Basic by A.J Watkins , C Kitcher [/B] I hope this is a bit clearer. Many thanks [/QUOTE]
