Question

in an electric circuit a battery and a bulb have been connected and battery consists of two cells of equal protein and tell difference is the bulb is not growing then which test will you perform in order to find out the reason for the bulb not made

Answer 1

All electric circuits have at least two parts: a voltage source and a conductor. The voltage source of the circuit in is a battery. In a home circuit, the source of voltage is an electric power plant, which may supply electric current to many homes and businesses in a community or even to many communities. The conductor in most circuits consists of one or more wires. The conductor must form a closed loop from the source of voltage and back again. In Figure 23.16, the wires are connected to both terminals of the battery, so they form a closed loop. The circuit in Figure 23.16 also has two other parts: a light bulb and a switch. Most circuits have devices such as light bulbs that convert electric energy to other forms of energy. In the case of a light bulb, electricity is converted to light and thermal energy. Many circuits have switches to control the flow of current through the circuit. When the switch is turned on, the circuit is closed and current can flow through it. When the switch is turned off, the circuit is open and current cannot flow through it.
