I am happy to provide a step-by-step guide on how to solve a circuit diagram with an ideal M voltmeter.

Step 1: Understand the Circuit Diagram
The first step in solving a circuit diagram with an ideal M voltmeter is to understand the components and connections in the circuit. Look at the attached figure and identify the different elements such as resistors, voltage sources, and the voltmeter itself.

Step 2: Identify the Unknown Voltage
In this circuit, the unknown voltage is the voltage across the 10 ohm resistor. This is the voltage that the ideal M voltmeter will read.

Step 3: Apply Ohm's Law
Using Ohm's Law (V=IR), we can calculate the voltage across the 10 ohm resistor by multiplying the current (I) flowing through it by its resistance (R). In this case, the current is given as 2 amps, so the voltage across the resistor is 2 x 10 = 20 volts.

Step 4: Understand Ideal M Voltmeter
An ideal voltmeter has infinite resistance, meaning that it does not draw any current from the circuit. Therefore, it does not affect the voltage in the circuit and will read the same voltage as the resistor it is connected to.

Step 5: Read the Voltage
Since the ideal M voltmeter is connected in parallel to the 10 ohm resistor, it will read the same voltage of 20 volts. This is the voltage across the 10 ohm resistor and is the answer to the given question.

Therefore, the correct answer is d) 20.0 volts.

In summary, to solve a circuit diagram with an ideal M voltmeter, you need to understand the circuit, identify the unknown voltage, apply Ohm's Law, and understand the properties of an ideal voltmeter. I hope this guide has helped you understand the process.
