Extend your thinking: household appliances are usually connected in a parallel circuit. why do you think it might be a problem if too many appliances are turned on at once? (hint: current in a wire also produces heat.)

There might be a problem of a lot of power being dissipated if too many

appliances are turned on at once.

We can infer from Ohm's law that as resistance decreases, the total current increases.

I= V/R

The power dissipated through the circuit is directly proportional to the square

of the current.

P= I²R

We can therefore state that the power dissipated via heat will be much when

too many appliances are turned on at once.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
