A filament bulb and a resistor are connected in series to a battery. Which of the following will contribute to the load of the circuit?
A. Bulb
B. resistor
C. Bulb and resistor
D. none
I'm thinking the resistor, but I'm unsure. Thanks
C bulb and resitor
To determine which component contributes to the load of the circuit, we need to understand the concept of load in an electric circuit.
In an electrical circuit, the load refers to the part of the circuit that consumes electrical energy and converts it into another form of energy, such as light, heat, or mechanical work. The load is responsible for drawing power from the power source, such as a battery or generator.
In this scenario, both the filament bulb and the resistor are connected in series to the battery. To determine which component contributes to the load, we need to consider the properties of each component.
A filament bulb is designed to produce light when electrical current passes through it. It has a filament that heats up and emits light. Therefore, the bulb consumes electrical energy and converts it into light energy. Consequently, the bulb acts as a load in the circuit.
A resistor, on the other hand, is a passive component that restricts the flow of electrical current. It converts electrical energy into heat energy. Since it dissipates electrical power in the form of heat, the resistor also functions as a load in the circuit.
To sum up, both the filament bulb and the resistor contribute to the load of the circuit. Therefore, the correct answer is C. Bulb and resistor.
