<span>The correct answer is D): resistors B and C. In fact, the energy per unit charge is equal to the voltage across the resistors. The electrical potential energy is in fact: </span>U=qV<span>, where q is the charge and V is the voltage; by rearranging the equation, we have </span>V= \frac{U}{q}<span>, therefore the voltage is the energy per unit charge. In the circuit in the figure, the resistors B and C are connected to the same points of the circuit (they are connected in parallel), therefore they have the same voltage, so they have the same energy per unit charge.</span>

Answer:

D. B and C

Explanation:

We have to find that which of the given is having same amount of energy per unit charge.

So we know that energy per unit charge is defined as potential.

V = \frac{U}{q}

so here we have to find in this circuit that which of the given resistors are at same potential.

So here we can see that resistance B and C are parallel to each other in this circuit and all the resistors which are in parallel to each other are always having same potential.

So B and C are having same potential energy per unit charge

If you are given force and time, you can determine power if you can know watts energy joules distance
shepuryov [24]

Answer:

distance

Explanation:

Distance is the missing quantity. It is needed to estimate the amount of work done by a force, and afterwards it is used to estimate the power, which is the work done over the time it took to complete it.

A car battery with a 12 V emf and an internal resistance of 0.11 Ω is being charged with a current of 56 A. What are (a) the pot
denpristay [2]

Answer:

Part a)

V = 18.16 V

Part b)

P_r = 345 Watt

Part c)

P = 672 Watt

Part d)

V = 5.84 V

Part e)

P_r = 345 Watt

Explanation:

Part a)

When battery is in charging mode

then the potential difference at the terminal of the cell is more than its EMF and it is given as

\Delta V = E + i r

here we have

E = 12 V

i = 56 A

r = 0.11

now we have

\Delta V = 12 + (0.11)(56) = 18.16 V

Part b)

Rate of energy dissipation inside the battery is the energy across internal resistance

so it is given as

P_r = i^2 r

P_r = 56^2 (0.11)

P_r = 345 W

Part c)

Rate of energy conversion into EMF is given as

P_{emf} = i E

P_{emf} = (56)(12)

P_{emf} = 672 Watt

Now battery is giving current to other circuit so now it is discharging

now we have

Part d)

V = E - i r

V = 12 - (56)(0.11)

V = 12 - 6.16 = 5.84 V

Part e)

now the rate of energy dissipation is given as

P_r = i^2 r

P_r = 56^2 (0.11)

P_r = 345 W
