a storage battery of emf 8V internal resistance 1 ohm is being charged by a 12 V d.c source using a 15 ohm resistor in series in the circuit. Calculate the current
I=(V1-V2)/(R1+R2) = (12-8)/(15+1)=
To calculate the current flowing through the circuit, we can use Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R):
I = V / R
In this scenario, the circuit consists of a 12V DC source, a 15-ohm resistor, and a storage battery with an EMF (electromotive force) of 8V and an internal resistance of 1 ohm.
First, let's calculate the total resistance of the circuit. Since the resistor and internal resistance are in series, we can add them together:
Total resistance (RT) = resistor + internal resistance
RT = 15 ohm + 1 ohm
RT = 16 ohm
Now, we can calculate the current using Ohm's Law:
I = V / R
I = 12V / 16 ohm
I = 0.75 A
Therefore, the current flowing through the circuit is 0.75 Amperes.
