Question
The current across the 3 ohm resistance in the given
circuit is:Solution
Here V = 5 v R1 = 3 ohm and R2= 4 ohm The total resistance in a series circuit is calculated by adding the individual resistances: R_total = R_1 + R_2 + R_3 + ... + R_n Resistance =Â 3 + 4 = 7 ohm Ohm's Law Equation : V = IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by circuit. I = V/R =Â 5/7 A
