\ A lightbulb has a resistance of 155 Ω when operating with a potential difference of 165 V across it. What is the current in the lightbulb (in mA)? mA (b) What If? What would be the current in the lightbulb (in mA) if it were used in Japan, where the potential difference across it would be 100 V? mA

Step 1
Ohm's Law states that \( I = \frac{V}{R} \), where \( I \) is the current, \( V \) is the voltage, and \( R \) is the resistance. Show more…
