Q: What is the potential difference across a 10-ohm resistor carrying a current of 3 A?
Solution:
Using Ohm's Law (V = I * R), V = 3 A * 10 Ω = 30 V.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10 ohms (Ω) and a current of 3 amperes (A).
Step 2: Recall Ohm's Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R). The formula is V = I * R.
Step 3: Substitute the values into the formula. Here, I = 3 A and R = 10 Ω.
Step 4: Calculate the potential difference. Multiply 3 A by 10 Ω to get V = 30 V.
Step 5: Conclude that the potential difference across the 10-ohm resistor is 30 volts (V).
