If we assume that the two electrodes in this experiment each have a static (nonchanging) net charge on them, how could you use your plot of equipotential surfaces to determine which electrode is more positively charged

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit
