Q: What is the voltage across a 10 ohm resistor carrying a current of 0.5 A?
Solution:
Using Ohm's law, V = I * R = 0.5 A * 10 Ω = 5 V.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have a resistor with a resistance of 10 ohms and a current of 0.5 amperes.
Step 2: Recall Ohm's law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). The formula is V = I * R.
Step 3: Substitute the values into the formula. Here, I = 0.5 A and R = 10 Ω.
Step 4: Calculate the voltage. Multiply 0.5 A by 10 Ω to get V = 5 V.
Step 5: Conclude that the voltage across the 10 ohm resistor is 5 volts.
