Formula & Methodology
The formula to calculate input current (I) is:
I = V / R
where V is the voltage and R is the resistance.
Real-World Examples
Let’s calculate input current for three scenarios:
- Scenario 1: V = 12V, R = 5Ω → I = 2.4A
- Scenario 2: V = 24V, R = 10Ω → I = 2.4A
- Scenario 3: V = 110V, R = 100Ω → I = 1.1A
