In a potentiometer, if the length of the wire is 20 m and the potential difference is 10 V, what is the voltage drop per meter?

In a potentiometer, if the length of the wire is 20 m and the potential difference is 10 V, what is the voltage drop per meter?

Step 1: Identify the total potential difference (voltage) given in the problem, which is 10 V.
Step 2: Identify the total length of the wire given in the problem, which is 20 m.
Step 3: Use the formula for voltage drop per meter, which is Voltage (V) divided by Length (L).
Step 4: Substitute the values into the formula: V/L = 10 V / 20 m.
Step 5: Perform the division: 10 V divided by 20 m equals 0.5 V/m.
Step 6: Conclude that the voltage drop per meter is 0.5 V/m.
