Answer:
The value of R and the internal resistance of the battery are 10.6 ohm and 2.45 ohm
Explanation:
Given that,
Emf of battery = 15.0 V
Voltage = 12.2 V
Power = 14.0 W
(a). We need to calculate the value of R
Using formula of power
Where, R = resistance
P = power
V = voltage
Put the value into the formula
(b). We need to calculate the internal resistance of the battery
Firstly we calculate the current
Using formula of current
Put the value of P and V into the formula
We calculate the internal resistance
Using formula of emf
Put the value into the formula
Hence, The value of R and the internal resistance of the battery are 10.6 ohm and 2.45 ohm
You're only asking 5 points for this question? it's kinda a lot :) just saying (i'm calculating it right now i'll comment the right answers)
