Ohm's Law => V = I/R where
V stands for voltage,
I stands for Current
R stands for resistance.
ATQ
we know V = 9 volts
and R = 1.5 ohm's
so we need to find I.
Lets modify our formula little bit
we know V = IR which we can write as I = V/R
so lets substitute the values in the formula.
I = 9/1.5
I = 6 A
Correct Option is A.
