Question

Household current in a circuit cannot generally exceed 15 for safety reasons. What is the maximum amount of charge taht could flow through this circuit in a house during the course of a 24 hour day

Answer 1

The current I is defined as the amount of charge Q flowing through a certain point in a time t:

`I= (Q)/(t)`
which can be rewritten as

`Q=It`
so, by using this formula we can calculate the maximum amount of charge that can flow in the circuit. In fact, the maximum current is I=15 A, while the time is

`t=24 h=86400 s`
so the maximum amount of charge is

`Q=(15 A)(86400 s)=1.30 \cdot 10^6 C`
