a) in parallel
b) 10 is not possible with given data
b) 10 is not possible with given data
elsavijay:
Pls cud u do it cuz all three in parallel for the first one as u said is not correct..and the second one is possible as I got it..but wasn't getting the first one and I need that one
umm...use parallel formula

Answer:sorry i don't have a pen or a pencil right now, but i can help you. first -make the three resistors in parallel with circuit..
Explanation:
Second - find the equivalent resistance by the formula 1/R'=1/30+1/5+1/10 == 1+6+3/30 == 10/30 == 1/3
1/R' = 1/3 (cross multiplying each other) R'=3 ohm . Mark me as brainliest and thank you forthe questions ..Regards .
