Question
the results of a short may include:
a) high voltage drop
b) a motor that turns slowly
c) a broken wire
d) a blown fuse
A short circuit causes a very low resistance path. According to Ohm's law \(I = \frac{V}{R}\), when \(R\) is very small, the current \(I\) is very large. A fuse is a safety device that melts and breaks the circuit when the current exceeds its rated value. So a blown fuse can be a result of a short - circuit.
A high voltage drop (\(V = IR\)) would occur when \(R\) is high (e.g., in an open - circuit or high - resistance component), not in a short - circuit (where \(R\) is low). A motor that turns slowly is usually due to insufficient voltage or mechanical issues rather than a short - circuit. A broken wire is an open - circuit condition, not a short - circuit.
