Answer:
Part a)
V = 15 Volts
Part b)
P = 180 Watt
Part c)
Rate = 720 Watt
Explanation:
Part a)
When battery is in charging then the potential difference of the terminals of cell is given by
here we know that
EMF = 12 volts
i = 60 A
r = 0.050 ohm
now we have
Part b)
Rate of thermal energy dissipated is the energy which is dissipating across the resistor
so here we have
P = 180 Watt
Part c)
Rate at which Energy stored inside the cell is the rate of electrical energy that is converted into the chemical energy
because I googled it and are you going there or something
Use the formula for energy stored between the plates of a capacitor:
where Q is he charge (given) and U is the electric potential (aka voltage), given.
The stored energy is 2.2 10^{-10} Joules.
The resistance of a conductor is inversely proportional to the cross sectional area of the conductor.
<u>Explanation:</u>
The resistors are used to resist or block the flow of current in any circuit. As per Ohm's law, resistance is inversely proportional to the current flow or charge in the circuit. But the resistance of a conductor will depend on the length of the conductor and cross sectional area of the conductor along with specific resistance of the material with which the conductor is made.
Here, Rho is the specific resistance, L is the length of the conductor and A is the cross sectional area of the conductor.
As the resistance offered by the conductor will be directly proportional to the length of the conductor and inversely proportional to the cross sectional area of the conductor. So the resistance of a conductor is inversely proportional to the cross sectional area of the conductor.
