A 10-ohm resistor has a voltage of 50 volts across it. What is the current flowing through the resistor?
Step 1: Identify the values given in the problem. We have a voltage (V) of 50 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 50 volts and R with 10 ohms: I = 50 V / 10 Ω.
Step 4: Perform the division. Calculate 50 divided by 10, which equals 5.
Step 5: State the result. The current flowing through the resistor is 5 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, expressed as I = V / R.
