Answer :
Answer:
I=0.89 Amp
Explanation:
Electric Energy
When an electric power source has a voltage V, with a current I, the power it delivers is given by
[tex]P=V.I[/tex]
The electric energy is the product of the power by the time elapsed
[tex]E=P.t[/tex]
Replacing the first equation into the second
[tex]E=V.I.t[/tex]
The question provides the values for E, V, and t, let's solve the above equation for I
[tex]\displaystyle I=\frac{E}{V.t}[/tex]
The values are
[tex]E=96\ KJ = 96,000\ J, V = 1.5\ Volts, t = 20\ h = 20*3,600 = 72,000\ sec[/tex]
[tex]\displaystyle I=\frac{96,000\ J}{1.5\ V\times 72,000\ sec}[/tex]
[tex]\boxed{I=0.89\ Amp}[/tex]
The current it provide will be "0.89 Amp".
Current and Voltage:
Given that,
- Voltage, V = 1.5 v
- Energy, E = 96 kJ or, 96000 J
- Time, t = 20 hours or, 72000 sec
We know the relation,
⇒ [tex]P=V.I[/tex] ...(equation 1)
and,
⇒ [tex]E = P.t[/tex] ...(equation 2)
From "equation 1" and "equation 2", we get
⇒ [tex]E = V.I.t[/tex]
Now
The Current be:
⇒ [tex]I = \frac{E}{V.t}[/tex]
By substituting the values,
[tex]= \frac{96000}{1.5\times 72000}[/tex]
[tex]= \frac{96000}{108000}[/tex]
[tex]= 0.89 \ Amp[/tex]
Thus the above answer is right.
