Answer:
46.a
In a parallel circuit, each device is placed in its own separate branch. The presence of branch lines means that there are multiple pathways by which charge can traverse the external circuit. Each charge passing through the loop of the external circuit will pass through a single resistor present in a single branch.
47.D kettle no.2
The most popular use for a kettle, whether it is stovetop or electric, is to make hot beverages. To make tea or coffee, all you really need to do is add water to your kettle and let it heat to the appropriate temperature
48.D electrical voltage
Let's say you have a 60-watt incandescent lightbulb and you are paying 12 cents per kWh of energy. Leaving the bulb on the whole day will therefore cost you: 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = approximately 20 cents in one day.
49.A cerecuit breakers
A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.
50.B open cercuit
You will receive a shock if you touch two wires at different voltages at the same time. You will receive a shock if you touch a live wire and are grounded at the same time. When a circuit, electrical component, or equipment is energized, a potential shock hazard is present.
