1.How much energy is given to each coulomb of charge passing through a 6 V battery ?
2. On what factors does the resistance of a conductor depend?
Answers
Step-by-step explanation:
Given that
Charge,q = 1 C
Potential difference V = 6 v
To find out
We need to find the energy given to each coulomb of charge passing through a 6 V battery.
Solution
Principle of conservation of energy
From the principle of conservation of energy, we know that the system’s work is equal to the energy supplied to that system.
The energy given to each coulomb of charge is equal to the amount of work required to move it.
Formula
Potential difference (V)= Work done (W) / Charge (q)
On rearranging the above formula, we get
Work done (W) = Potential difference X Charge
Put the value of V and q in the above equation, we get
Work done (w) = 6 X 1
Work done = 6 Joules
Therefore, the energy is given to each coulomb of charge passing through a 6 v battery is 6 J.
Step-by-step explanation:
1 .Given ,
Charge Q = 1 c , potential , V = 6 V
Energy = W = VQ = 6 V × 1 C
= 6 J
2. Resistance of a conductor depends on its length, area of cross-section, temperature and material of which it is made.
