Question

6 sam is in the kitchen making brownies. he melts the butter in the microwave, turns on the oven to preheat, and uses the electric mixer all at the same time. which best explains why sam can turn the mixer off without the other appliances turning off as well?
a the circuits are wired in series, and when one appliance turns off, the others can still run
b the circuits are wired in parallel, and when one appliance turns off, the others will switch to series circuits for power.
c the circuits are wired in series, and when one appliance turns off, the others will switch to parallel circuits for power
d the circuits are wired in parallel, and when one appliance turns off, the others can still run

Explanation:

In parallel circuits, each component has its own separate path for current. So, if one appliance (like the mixer) is turned off (breaking its path), the other appliances (microwave, oven) still have their own paths intact and can continue running. In series circuits, all components are in a single path. If one component is off (open circuit), the entire circuit is broken and all components stop. Option A is wrong about series - parallel difference. Option B is wrong about switching to series. Option C is wrong about series circuit properties. Option D correctly states that parallel - wired circuits allow one appliance to turn off while others run.

Answer:

D. The circuits are wired in parallel, and when one appliance turns off, the others can still run
