Questions & Step-by-Step Solutions
If a circuit has a total resistance of 10 ohms and a total voltage of 50V, what is the total current?
Correct Answer: 5 A
Step 1: Identify the total voltage in the circuit, which is given as 50 volts.
Step 2: Identify the total resistance in the circuit, which is given as 10 ohms.
Step 3: Recall Ohm's law, which states that current (I) equals voltage (V) divided by resistance (R).
Step 4: Plug the values into the formula: I = V / R.
Step 5: Substitute the values: I = 50V / 10 ohms.
Step 6: Calculate the result: 50 divided by 10 equals 5.
Step 7: Conclude that the total current in the circuit 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.
