Questions & Step-by-Step Solutions
A resistor of 10 ohms is connected to a 20V battery. What is the current flowing through the resistor?
Correct Answer: 2 A
Step 1: Identify the values given in the problem. We have a resistor of 10 ohms and a battery of 20 volts.
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 = 20 volts and R = 10 ohms.
Step 4: Calculate the current by dividing 20 volts by 10 ohms. So, I = 20V / 10Ω.
Step 5: Perform the calculation. 20 divided by 10 equals 2.
Step 6: Conclude that the current flowing through the resistor is 2 amperes (A).
Ohm's Law – Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.
