Find the current through a resistance 2 ohm if the voltage across the resistance is 6 V

Step 1: Given: Resistance = 2\(\Omega\)

Voltage = 6 V

To find: Current, I =?

Step 2: Calculating current

From Ohm’s law, we know that,

V = IR

I = V/R

I = 6/2

I = 3 A

Therefore the value of the current through the resistance is 3 A.
