Answer:
- The charge on the plates will increase with time
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
- The current through the circuit starts high and then drops exponentially
Explanation:
<u>Case : An uncharged capacitor is connected to a resistor and a battery in a closed circuit.</u>
- The charge on the plates will increase with time
applying this equation : Q = as the value of (t) increases the value of Q increases i.e. charge on the plates
- The potential difference across the capacitor starts with zero and then increases gradually to a maximum value
applying this equation : V =
- The current through the circuit starts high and then drops exponentially
current : I =
Answer:
5000J
Explanation:
Given in the question that
Heat added to the coffee cup is, ΔS = 20 J/K
The temperature of the coffee, T = 250 K
Now, using the formula for the entropy change
...........(1)
Where,
ΔS is the entropy change
ΔH is the enthalpy change
T is the temperature of the system
substituting the values in the equation (1)
we get
ΔH=250×20
ΔH=5000 J
