IN PARALLEL COMBINATION
1/R=1/8+1/12
1/R=6+4/48
R=48/10
R=4.8 OHM
IN SERIES COMBINATION
R=7.2+4.8
R=12.0 OHM

1. Magnesium

2. The surface appear white due to reaction of magnesium and oxygen present in air.

3. Magnesium burn with a dazzling white flame and changes into a white powder.

Q (6) 8 ohm and 12 ohm resistor are in parallel connection

Total effective resistance in parallel = 8×12/8+12

= 4.8 ohm

--> 4.8 ohm + 7.2 ohm ( they are in series connection )

20 ohm
