Homework Statement
We are given two identical thermophores. It is known that one of them can boil a liter of water in t = 600 s.
How much time would it take to boil one liter of water if we used two of these thermophores, connected
a) in a series circuit
b) in a parallel circuit
Voltage: 230 V
t = 600 s
U = 230 V
I1 = I2
Homework Equations
W - energy required to boil water
W = UIt
The Attempt at a Solution
a) series circuit
Since the thermophores are in a series, each of them will share the same current, thus:
W = (UI+UI)t = 2UIt => t = 300 s
b) parallel circuit
The thermophores are in a parallel connection, which means that they will share the current, and so each of them will be empowered with the current 0.5I
W = 0.5I U t + 0.5 I u T = UIt => t = 600 s
However, I doubt that this solution is valid.
Could you, please, give me some tips or reference how to tackle this problem?
Thank you very much in advance.
