Question

An electric circuit has an expected current of 80 amps. An electrician measures the current in the circuit at 120 amps. Which statement provides a possible explanation for this observation?(1 point) Responses The circuit has an extra resistor. The circuit has an extra resistor. There is not enough voltage in the circuit. There is not enough voltage in the circuit. A resistor in the circuit is broken. A resistor in the circuit is broken. There is not enough electrical energy in the circuit.

Answer 1

The statement "A resistor in the circuit is broken" provides a possible explanation for the observation that the measured current is higher than expected. If a resistor is broken or has a higher resistance value than intended, it can lead to a reduction in total resistance in the circuit, resulting in an increase in current if the voltage remains the same (according to Ohm's Law: V = IR).

The other options do not logically explain the increase in current:
- An extra resistor would typically increase resistance and decrease current.
- Not enough voltage would result in lower current, not higher.
- Not enough electrical energy would not directly correlate to higher current; instead, it would suggest insufficient capacity.

Therefore, the broken resistor is the most fitting explanation among the options provided.
