Step-by-step Solution

Given: - Voltage reading of the voltmeter is 8 V. - Resistance is 12 Ω. We can use Ohm's Law to find the electric current intensity passing through the resistance. Ohm's Law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Ohm's Law formula: \( I = \frac{V}{R} \) Substitute the given values: \( I = \frac{8}{12} \) Now, we can calculate the electric current intensity passing through the resistance. Calculate the value by following steps: - step0: Calculate: \(\frac{8}{12}\) - step1: Reduce the fraction: \(\frac{2}{3}\) The electric current intensity passing through the resistance is \( \frac{2}{3} \) A or approximately 0.6 A. Therefore, the closest option to this value is (B) 0.8 A.

Quick Answer

The electric current intensity passing through the resistance is approximately 0.6 A, closest to (B) 0.8 A.
