Suppose a battery output a voltage of 9 volt. Calculate how many joules of energy are imparted to every individual electron moving through this battery?
Q=IVt=(q/t)Vt=qV=eV= =1.6•10⁻¹⁹•9=1.44•10⁻¹⁸J.
To calculate the amount of energy imparted to individual electrons moving through a battery, we can use the equation:
Energy = Charge x Voltage
The charge of an electron is approximately 1.6 x 10^-19 coulombs.
Given that the voltage of the battery is 9 volts, we can calculate the energy imparted to each electron as follows:
Energy = (1.6 x 10^-19 C) x (9 V)
= 1.44 x 10^-18 joules
Therefore, approximately 1.44 x 10^-18 joules of energy are imparted to every individual electron moving through the battery.
To calculate the energy imparted to each individual electron moving through a battery, we need to know the charge of an electron (e) and the voltage of the battery (V).
The charge of an electron is approximately 1.6 x 10^-19 coulombs (C).
The energy (E) imparted to each electron can be calculated using the formula:
E = q * V
where q is the charge of an electron, and V is the voltage of the battery.
Substituting the values, we have:
E = (1.6 x 10^-19 C) * (9 V)
E ≈ 1.44 x 10^-18 joules (J)
So, each individual electron moving through this battery imparts approximately 1.44 x 10^-18 joules of energy.
