C) |V1|+|V2|<|V|
D) |V1|=|V2|=|V|
E) |V1|=|V2|<|V|
Which one of the following is true for the magnitudes of the currents?
A) |I1|+|I2|>|I|
B) |I1|+|I2|=|I|
C) |I1|+|I2|<|I|
D) |I1|=|I2|=|I|
E) |I1|=|I2|<|I|
Explanation / Answer
B) V1=V2
since in parallel , Voltage across resistances remain same.
.A) I1>I2
as the Voltage is same across two resistances, the current is inversly propotional to resistance. according to ohm's law. hence smaller resistance will have greater current in it
D) |V1|=|V2|=|V|
Since resistances and battery are connected in parallel
B) |I1|+|I2|=|I|
sum of the current in the two resistances is same as the current coming from the battery
