The voltage at the end of the conductors is 12V
Explanation:
Given:
Resistance, R = 12Ω
Heat released, H = 144J
Time, t = 12s
Voltage, V = ?
According to joule's law:
H = I²RT
where,
I is the current
T is the time
R is the resistance
The above formula can also be written as:
[tex]H = \frac{V^2}{R} t[/tex]
where,
V is the voltage
On substituting the value in the formula we get:
[tex]144 = \frac{V^2}{12} X 12\\\\V^2 = 144\\\\V = 12[/tex]
Therefore, the voltage at the end of the conductors is 12V
