Integrated Concepts A short circuit in a 120-V appliance cord has a 0.500- resistance. Calculate the temperature rise of the 2.00 g of surrounding materials, assuming their specific heat capacity is 0.200 cal/g.°C and that it takes 0.0500 s for a circuit breaker to interrupt the current. Is this likely to be damaging?
