Question

microwave
solar panel system
portable power bank

1. does your home have fuses or a circuit breaker? how does this device help protect your home?
2. click the following link: https://phet.colorado.edu/sims/html/circuit-construction-kit-ac-virtual-lab/latest/circuit-construction-kit-ac-virtual-lab_all.html

create an ac current using a battery, wires, light bulb and \ac voltage\. add a voltage chart to either side of the light bulb. watch what happens to the voltage in the circuit.
insert a picture of your circuit below.

Explanation:

For the table (energy type categorization):

• A microwave uses alternating current (AC) from the wall outlet to operate.
• A solar panel system generates direct current (DC) from sunlight, which can be converted to AC for home use, but the core output is DC.
• A portable power bank stores and supplies direct current (DC) to charge devices.

For question 10:

Fuses and circuit breakers are overcurrent protection devices. When an excessive current (from a short circuit or overloaded circuit) flows, a fuse's metal wire melts to break the circuit; a circuit breaker trips (switches off) to interrupt the current. Both prevent overheating of wires, which could cause fires or damage electrical devices.

For question 11:

1. Access the provided PHET simulation link.
2. Drag an AC voltage source (not a battery, as batteries produce DC) from the components menu, along with wires, a light bulb, and two voltage charts (voltmeters).
3. Connect the AC voltage source, light bulb, and wires in a closed loop.
4. Attach one voltage chart across the AC source and another across the light bulb.
5. Activate the simulation: the voltage charts will show that the voltage oscillates sinusoidally (positive and negative values alternating) across both the source and the bulb, matching the nature of AC current. A visual of this circuit would show the closed loop with the AC source, bulb, and two voltmeters attached to either side of the bulb and the source.

Question 10 Answer:

Most homes have either fuses or circuit breakers. These devices protect the home by detecting and interrupting excessive electrical current (caused by short circuits or overloaded circuits). Fuses melt a metal element to break the circuit, while circuit breakers trip a switch. Both prevent wire overheating, fire risks, and damage to electrical equipment.

Question 11 Answer:

1. Open the PHET circuit simulation via the provided link.
2. Use an AC voltage source (not a battery, as batteries produce DC), wires, a light bulb, and two voltage charts to build a closed circuit.
3. Attach one voltage chart across the light bulb and one across the AC source.
4. Run the simulation: the voltage charts will display a sinusoidal, oscillating voltage (swapping positive and negative values) across both the bulb and the source, demonstrating the alternating nature of the current.

(Note: A picture of the circuit would show a closed loop with the AC generator, light bulb, and two voltmeters connected in parallel to the bulb and generator respectively.)
