A 10 Ω resistor is connected to a 20 V battery. What is the current flowing through the resistor?
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: Write down Ohm's law formula, which is V = I * R, where I is the current.
Step 3: Rearrange the formula to solve for current (I). This gives us I = V / R.
Step 4: Substitute the values into the formula. Replace V with 20 volts and R with 10 ohms: I = 20 / 10.
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).
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.
