When an through each resistor before it reaches the battery again?

Answer 1

(1) R = AB X10 + DY Brown Red Yellow A = 1 B =2 c = 4 A B C D R = 12x10 + 20% 2. Green Grey A = 5 38 Green (=5 R = 58x105 & 20%. White > A = 9 Voilet B= 7 Brown (= 1 R = 97x10 + 20% series with resisistors. Parallel across a resistor. 4. Ameter must Place in 5. we must place in Go symbol i ori, Unit Ampere (1) Symbo - R Unit ohm ( 2 ) 9) V = I x R L at constant Temperature 2 (100 Two resistors is said to be in parallel if they have same voltage R R2 o yes:
