Question

1. a short circuit is a type of closed circuit that allows current to bypass the load.

this leads to a circuit with very low _______________ and results in an

extremely high amount of _______________. (select all that apply.)

voltage, current

ohms, amperes

resistance, ohms

Explanation:

Analyze the definition of a short circuit

Using the Electrical Resistance knowledge point

$$ R_{\text{short}} \approx 0\,\Omega $$

Determine the effect on current

Using the Electric Current knowledge point

$$ I = \frac{V}{R} \to \infty \quad \text{as} \quad R \to 0 $$

Evaluate the given options

• voltage, current: Incorrect. A short circuit leads to very low resistance, not very low voltage.
• ohms, amperes: Correct. Ohms measure resistance (which becomes extremely low), and amperes measure current (which becomes extremely high).
• resistance, ohms: Incorrect. Both terms refer to the opposition to current flow, rather than one low and one high quantity.

Answer:

• voltage, current
• ohms, amperes (Correct answer)
• resistance, ohms
