Calculation of Current and Voltage

To find the current and voltage in the given circuit, we can use Ohm's Law and the concept of internal resistance.

The electromotive force (EMF) of the source is given as 17V, and the internal resistance is 5Ω. The resistance of each resistor is 28Ω.

Let's denote the current flowing through the circuit as I. According to Ohm's Law, the voltage across a resistor is equal to the current multiplied by the resistance.

The total voltage across the circuit can be calculated as the sum of the voltage across the source and the voltage across the internal resistance:

Total Voltage = EMF - (Current * Internal Resistance)

We can rearrange this equation to solve for the current:

Current = (EMF - Total Voltage) / Internal Resistance

Now, let's substitute the given values into the equation:

EMF = 17V Internal Resistance = 5Ω Resistance of each resistor = 28Ω

To find the total voltage, we need to calculate the voltage across the resistors. Since the resistors are connected in series, the total resistance is the sum of the resistances of each resistor:

Total Resistance = Resistance of each resistor * Number of resistors

In this case, there is only one resistor, so the total resistance is equal to the resistance of that resistor:

Total Resistance = 28Ω

Now, we can calculate the total voltage using Ohm's Law:

Total Voltage = Current * Total Resistance

Substituting the values into the equation:

Total Voltage = I * 28Ω

Finally, we can substitute the values into the equation for the current:

Current = (17V - Total Voltage) / 5Ω

Let's calculate the current and voltage using these equations.

Calculation:

First, let's calculate the total voltage:

Total Voltage = I * 28Ω

Next, let's calculate the current:

Current = (17V - Total Voltage) / 5Ω

Now, let's substitute the equation for the total voltage into the equation for the current:

Current = (17V - (I * 28Ω)) / 5Ω

Simplifying the equation:

Current = (17V - 28Ω * I) / 5Ω

To solve this equation, we need to find the value of I that satisfies it. We can use numerical methods or algebraic techniques to find the solution. However, without knowing the specific value of the total voltage, it is not possible to provide an exact numerical answer.

Please provide the value of the total voltage, and I will be able to calculate the current and voltage in the circuit.
