Two identical appliances are connected to the same household circuit and the circuit breaker trips. Which of the following is true (there may be more than one correct answer) (2 points): (A) If the breaker is reset and only one appliance is connected, the breaker will not trip. (B) Connecting only one appliance on this circuit might not trip the breaker again. (C) Each appliance had too low a resistance to work with a normal 120-V circuit breaker. (D) The appliances together had a total resistance that was too low to work with a normal 120-V circuit breaker.

Explanation:

Circuit breaker trips due to excess current . Appliances are connected in parallel in which resistance becomes less . If only one appliance is connected then the current becomes low because of high resistance due to only one appliance . So breaker may not trip or may trip because resistance of  even single appliance may be quite low so current may still be high.

So B ) is  correct .

So C ) is also correct.

So D ) is also correct.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
