To determine the magnitude of the potential difference across the 20 ohm resistor, we can use Ohm's Law, which relates the potential difference (V), current (I), and resistance (R) in a circuit.
In the given diagram, the potential difference across the 20 ohm resistor can be found using the formula:
V = I * R
To apply Ohm's Law, we need to know the value of the current flowing through the 20 ohm resistor. Unfortunately, the diagram you provided does not include any information about the current.
If you have additional information about the current in the circuit, please provide it so that we can calculate the potential difference across the 20 ohm resistor.
