Questions & Step-by-Step Solutions
If a circuit has a total voltage of 10V and a total current of 2A, what is the total resistance in the circuit?
Correct Answer: 5Ω
Step 1: Identify the total voltage in the circuit, which is given as 10V.
Step 2: Identify the total current in the circuit, which is given as 2A.
Step 3: Recall Ohm's Law, which states that Resistance (R) equals Voltage (V) divided by Current (I).
Step 4: Substitute the values into the formula: R = V/I.
Step 5: Calculate the resistance: R = 10V / 2A.
Step 6: Perform the division: 10 divided by 2 equals 5.
Step 7: Conclude that the total resistance in the circuit is 5Ω.
Ohm's Law – Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor.
