Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Current doesn't follow vector addition rules, so despite having magnitude and direction they are not considered as vectors. see image, here resultant current at a junction by vector addition : 5√2 experiments : 10 therefore vector approch is wrong. so it proves current is added algebraically, these are experimental results when current is measured by ammeter at junction. it suggests that direction of electricity just represent the flow( which is govern by medium in which it is flowing) not its direction in space. hence current is a scalar.
