Since you haven't given us the list of options.... we cannot help you !
It is a safety device. It is not an essential part of the circuit.
Yes, a circuit is a part of a light bulb. It is designed to provide the necessary electrical connection for the bulb to receive power and emit light. Without the circuit, a light bulb would not be able to function properly.
By definition an electrical circuit is a route or path that starts and finishes at the same place. So there is no part of an electrical circuit that is not necessary, because if there were it would not be an electrical circuit.An electrical circuit needs a power source. Conductors to transmit the voltage from the power source to the load. The final component of the electrical circuit is the load that you want to energize.If you remove any of the components there will be an open circuit and the load will be impossible to operate.
when a light is on it is part of a scolde circuit
A small capacitor can be part of an integrated circuit.
It is often necessary to wire crossing
A closed circuit is a circuit where current can flow because it forms a continuous path, while a complete circuit is a closed circuit that includes all necessary components like a power source, load, and conductive path. So, a closed circuit can be a complete circuit if it has all the necessary components connected together.
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
The purpose of the battery in a circuit is to wive energy to the circuit
No, the aorta is part of the systemic circuit. The pulmonary circuit consists of the pulmonary artery and vein.
In seris circuit the positive part adjust with negative part successively whole circuit
It is not "necessary" for oscillation to occur in any "arbitrary" circuit. It depends on the design objectives. Please be more specific, and restate the question.
