The current through N will also change, as the resultant resistance changes when lamp M breaks.ravsterphysics said:

Current in a circuit refers to the flow of electric charge through a conductor, such as a wire. It is measured in amperes (A) and is essential for the operation of electrical devices.
Current can be measured using an ammeter, which is a device that is connected in series with the circuit and measures the flow of charge through a specific point in the circuit.
According to Ohm's Law, the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance. This means that as the voltage increases, the current also increases, but as the resistance increases, the current decreases.
A bulb, or any other electrical load, affects the current in a circuit by creating resistance. This resistance causes a decrease in the current, which in turn causes the bulb to light up. The brighter the bulb, the higher the current flowing through it.
No, current cannot flow without a complete path or circuit. This means that there must be a continuous loop of conductive materials for the current to flow through. If there is a break or gap in the circuit, the current will not flow.
