Question: What is the current flowing through a 15Ω resistor connected to a 45V battery?

Options:

Correct Answer: 3A

Solution:

Using Ohm\'s law, I = V/R = 45V / 15Ω = 3A.

What is the current flowing through a 15Ω resistor connected to a 45V battery?

Step 1: Identify the values given in the problem. We have a resistor of 15 ohms (Ω) and a battery of 45 volts (V).
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. Here, V = 45V and R = 15Ω.
Step 4: Calculate the current by dividing 45V by 15Ω. So, I = 45V / 15Ω.
Step 5: Perform the division. 45 divided by 15 equals 3.
Step 6: Conclude that the current flowing through the resistor is 3 amperes (A).
