Q
Q: What is the current through a 10 ohm resistor connected to a 20V battery?
Solution:
Using Ohm's law, I = V/R, we have I = 20V / 10 ohms = 2 A.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have a voltage (V) of 20 volts and a resistance (R) of 10 ohms.
Step 2: Recall Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R). The formula is I = V / R.
Step 3: Substitute the values into the formula. Replace V with 20 volts and R with 10 ohms: I = 20V / 10 ohms.
Step 4: Perform the division. Calculate 20 divided by 10, which equals 2.
Step 5: State the result. The current (I) through the resistor is 2 amperes (A).
