Calculation of Current in the Rheostat and Voltage across the Battery

To find the current in the rheostat and the voltage across the battery, we can use Ohm's Law. Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.

Given information: - Battery electromotive force (EMF): 6 V - Internal resistance of the battery: 0.5 Ω - Resistance of the rheostat: 5.5 Ω

Let's calculate the current in the rheostat and the voltage across the battery.

Using Ohm's Law, we can calculate the current in the circuit:

Current (I) = Voltage (V) / Total Resistance (R)

The total resistance in the circuit is the sum of the internal resistance of the battery and the resistance of the rheostat:

Total Resistance (R) = Internal Resistance + Rheostat Resistance

Substituting the given values:

Total Resistance (R) = 0.5 Ω + 5.5 Ω = 6 Ω

Now, we can calculate the current:

Current (I) = 6 V / 6 Ω = 1 A

Therefore, the current in the rheostat is 1 A.

To find the voltage across the battery, we can use Ohm's Law again:

Voltage (V) = Current (I) * Total Resistance (R)

Substituting the values:

Voltage (V) = 1 A * 6 Ω = 6 V

Therefore, the voltage across the battery is 6 V.

Conclusion

The current in the rheostat is 1 A, and the voltage across the battery is 6 V.

Please note that the information provided is based on the given values and calculations using Ohm's Law.
