Question

1)Four resistors of resistances 5 ohms each are connected in parallel. Calculate the effective resistance of the combination. 2)Write the name of the compound and deduce its molecular mass: 3 3) Give chemical reactions for below: 1) Aluminum oxide reacts with hydrogen fluoride 2) Sodium carbonate reacts with dil. Hydrochloric acid

Answer 1

Answer:

20 ohms

Explanation:

R1=5 ohms

R2=5 ohms

R3=5 ohms

R4=5 ohms

Effective resistance Rs=R1=R2+R3=R4

                                     =5+5+5+5

                                   

Therefore, the effective...
