Question

is a current of 4 a flow into a bulb how much current flows out of the bulb​

Answer 1

Answer:

Current flowing through a bulb is similar to the water current flowing through a faucet (or tap). Water enters the tap from the supply at a high pressure (analogous to voltage); however, if the faucet is only slightly open providing a high resistance, the pressure on the output side will be much lower. The water current (volume of water) flowing through the faucet will be the same on the input side and the output side. The pressure drop (analogous to voltage drop) multiplied by the current represents the energy dissipated in the faucet or bulb.
