Problem 8

Given information

There is a 60W bulb lit in a room. It is required to understand the total resistance of the room's circuit when an additional 100W bulb turns on with the 60W one.

Step-by-step explanation

Resistance of a circuit is directly proportional to the voltage and inversely proportional to the current passing through the circuit. It is indicated by the formula  , where V is the voltage and I is the current flow.
