Question

When you touch your figures (resistance 1000 ohm) to terminate calculate the current through your fingers? How An electric heater is rated 300W 120V. A home circuit breaker can withstand 15 A of current: any current higher will cause your breaker to switch off. How many heaters can be safely operated in the circuit, before it switches off? An electric toy that consumes 60 W of power draws what amount of current, in amps, from a normal wall outlet of 120 V? Is this toy dangerous? Explain your answer in terms of "Killer Amps".

Explanation / Answer

8 )

given

P = 60 W

V = 120 volts

using P = V X i

i = P / V

i = 60 / 120

i = 0.5 A

it is not dangerous because the current is only 0.5 A

it is nearly equal to DC current..
