Two bulbs of 100 W and 40 W are connected in series. The current through the 100 W bulb is 1 A. The current through the 40 W bulb will be :(a) 0.4 A (b) 0.6 A (c) 0.8 A (d) 1 A
(d) 1 A
Explanation
We know that in a series, the current through each device remains the same. Therefore, the current through the 40W bulb will also be 1A.
Series Connection is the connectivity of multiple components (e.g bulb) connected end-to-end in a line to form a single path through which current can flow.
In simple terms, Series Connection is the connectivity of multiple components in which the positive terminal of one component is connected to the negative terminal of the next component (and it keeps repeating if there are more than two components).
In this connection, the electrical circuit, components are arranged in a line, and the same current flows through all the components in the circuit. The current in this connection has only one path.
When the resistors are placed in a series circuit, the voltage across each resistor is different, even though the current flow is the same through them all. If one component breaks down in this connection, the whole circuit will burn out.
