Question: What is the current flowing through a 10Ω resistor connected to a 20V battery? (2021)

Options:

Correct Answer: 2 A

Exam Year: 2021

Solution:

Using Ohm\'s law, I = V/R = 20V/10Ω = 2 A.

What is the current flowing through a 10Ω resistor connected to a 20V battery? (2021)

Step 1: Identify the values given in the problem. We have a resistor of 10 ohms (Ω) and a battery of 20 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 = 20V and R = 10Ω.
Step 4: Calculate the current by dividing 20V by 10Ω. This gives us I = 20V / 10Ω.
Step 5: Perform the division. 20 divided by 10 equals 2.
Step 6: Conclude that the current flowing through the resistor is 2 amperes (A).
