How to calculate the electric current drawn by light bulb

WebSo, by closing this switch, you're essentially removing R2 from the circuit. The current will just go through R1, and then follow the path of least resistance, literally. And so, in this situation, our current is going to be 12 volt divided by, you essentially just have one resistance, divided by R1. So, when you closed the circuit, you've ... WebSince the current must leave, then it next reaches the second light bulb, where the same story is true- the current is the same on both sides of the bulb. In fact, the current can only change when there is a junction, and even then the total amount of current entering a junction is equal to the total amount of current leaving a junction. WebJun 29, 2024 · How to calculate the ohms of a light bulb? For example, a 100 watt light bulb operating on 120 volts AC will have\r 144 ohms of resistance and will draw 0.833 Amps. Enter 100 in the\r Watts field and 120 in the Voltage field and press Calculate to find\r the resistance and current. Fields should be reset to 0 before each\r new calculation. first aid kit compliance australia
